3D tablet talk has intensified following whispers that HTC is preparing a dual-camera 3D version of its Flyer, leaked through factory-line snaps today.

The pictures surfaced from a factory in China and show a familiar part of the Flyer body with two cameras instead of one.

The 2D HTC Flyer has only been on shelves a few months. The company already offers three-dimensional content on the go through its 4.3in HTC Evo 3D handset.

Upping this to 7in could be an interesting prospect, but with a price hike likely, and non-3D versions available, how will HTC persuade Flyer buyers the costly feature is worth the extra wad?

It seems folk aren't too convinced by 3D at all and besides, what do you do when some other guy owns the glasses-free 3D patents? ®
