Rumours Apple intends to launch a larger iPad Pro tablet continue to linger and the early previews of iOS 9 appear to contain perhaps the most convincing evidence yet.
Independent iOS developer and code sleuth Steve Troughton-Smith (via CNET) has spotted a scalable keyboard within iOS 9, which he says could be a sign Apple has plans to boost the footprint of its tablet range.
The alternate keyboard features a new row of symbols, while it also squeezes in a dedicated caps lock key, previously unseen within other versions of iOS.
The keys also happen to be more spread out than on the standard keyboard, Troughton-Smith says, backing up the claims with screenshots posted to Twitter.
Speculation has been rife over the last couple of years, suggesting Apple wishes to launch a 12.9-inch version of its pioneering iPad, geared towards business users and professionals.
Although Apple has not addressed the rumours, but the suggestion is the Pro version would suit those who wish to ditch their laptop for a touchscreen solution.

Apple launched iOS 9 at WWDC early this month, but so far it is only in the hands of the firm’s army of third-party app developers.
Whether the evidence uncovered by Troughon-Smith within the early beta means a larger iPad will arrive alongside the annual refresh this autumn remains to be seen. Today's discovery at least makes it look more likely.
