The firm is also hoping the larger screen will help it differentiate the iPad from the big screen iPhone 6 Plus.

It is also believed to include a all-new Bluetooth stylus accessory with pressure sensitivity, and a new pressure sensitive screen.

'Alongside the new iPhones, new Apple TV, new Apple Watch bands, and a gold anodized version of the Apple Watch Sport, Apple plans to debut a pair of new iPads on Wednesday: the larger iPad Pro and a new iPad mini,' claims 9to5mac. 

While Apple still plans to announce the device this week, open up pre-orders in October, and begin shipping in November, we understand that the first shipments may fall towards the end of November, the site says.

It claims the gadget could cost up to $1,000, putting it on a similar footing to the firm's MacBook laptop. 

According to John Paczkowski of Buzzfeed, the new Apple TV will boast universal search, allowing users to enter the name of a program and find out where they can watch it, from a number of providers like Netflix and iTunes.

Currently finding TV shows online can be difficult, with provider's like Amazon, Hulu and Netflix all competiting, and constantly changing their catalogues. 

Apple's universal search could solve this - and also make sure user's get the best price for content by showing all of the available alternatives.

'Essentially, you’ll be able to search for a show or movie once, and see results from all sorts of different sources,' said Paczkowski.

Apple is also believed to be unveiling a new touchscreen remote control, and will add support for wireless gamepads to the new product, set to be unveiled alongside its latest iPhones.

'According to sources with knowledge of the product, the fourth-generation Apple TV will actively compete for TV gamers with updated hardware, software, and peripherals that will debut at Apple’s September 9 event in San Francisco,' 9to5mac claims.

'One of the next Apple TV’s tentpole features will be near-universal Siri control, a feature hinted at in Apple’s invitation to the event. 

'But the other will be deep support for gaming, representing Apple’s largest-ever effort to lure players from traditional consoles.' 

Previous reports have hinted at the specification of the new iPad.

One person familiar with Apple's future product plans has revealed that the company is in fact working on an all-new iPad with a larger 12.9-inch display, according toAppleInsider. 

This person said that Apple is expected to include an NFC radio within the new 12.9-inch iPad.

While tap-to-pay functionality in an iPad is unlikely, the inclusion of NFC could allow for an 'iPad Pro' to serve as a payment receiving terminal for Apple Pay.

The inclusion of NFC could also allow for simplified pairing with accessories, such as the new stylus said to be in the works.

The source also indicated that the jumbo-sized iPad will sport a new touchscreen with improved touch latency.  

Apple's next-generation iPhone, referred to colloquially as the 'iPhone 6s,' will also feature the Force Touch input that is currently available on the Apple Watch and latest MacBooks, it is believed.

The iPad Pro is also expected to have a USB-C input, though they didn't indicate whether it would be a new, second port option, or if USB-C would replace the Lightning connector found on current iPads. Cases based on allegedly leaked 'iPad Pro' designs  

The big screen tablet is believed to be planned for release towards the end of the year. 

Rhoda Alexander, an analyst at market researcher IHS, said the pans were already well advanced.

'Our supply side (sources say) it's a go for 2015,' Alexander told FoxNews.com.

'The release timing is fuzzy, It may not appear until Q4 (fourth quarter) with the other iPad updates. 

'We are, however, getting input from both the component and [product] side that this is a real product, and part of their 2015 building plan.'

Apple CEO Tim Cook, in the company's most recent earnings conference call in January, talked about the iPad's future. 

'Over the long arc of time the iPad is a great business,' he said. 

'I also have visibility obviously of what's in the pipeline and feel very, very good about that.' 

Earlier this month a pose on Chinese networking site Weibo leaked what it claimed were the specs for the device. 

Apparently, the tablet will feature a 12.9-inch display with 2K resolution, and a 7mm thin profile. 

The leak also said the tablet is supposed to weigh 700g and pack a large 11,000 mAh battery, significantly bigger than the iPad Air 2's 7,340 mAh battery.

Late last year a leaked design for a case revealed more details of Apple's much rumoured iPad tablet.

According to French blog nowhereelse.fr, the case is from a 'reliable source' which has previously given them advance details of Apple's product, which the firm is notoriously secretive about.

It 'would be equipped with a screen measuring from 12.2 to 12.9 inches diagonally,' it says.

The tablet is also expected to have four speakers, and could even featur two charging ports allowing it to remain plugged in when in either portrait of landscape mode. 

It comes weeks after an image was leaked that appeared to be a mould for the device.

The photo was reportedly taken at Apple manufacturer Foxconn's factory in China and is said to measure approximately 12 inches high by 8.7 inches wide.

It follows a leaked sketch from last week that claimed to show one corner of the so-called megapad, iPad Pro or iPad Air Plus.

The latest image was posted on Chinese social network Weibo. 

If the rumours are true, the iPad Pro would be significantly larger than the current iPad Air 2.
