Sony reveals more details on PS Vita

US Carrier, 3G

One of the two PS Vita versions offers 3G connectivity and the device will be sold through cell-phone provider AT&T exclusively in the US - but no word on AT&T data plans and pricing yet. Vita cannot be used as a cell phone and the VoIP support is unclear. Sony also says the console will not be region specific.

Games medium

There's no Universal Media Discs (UMD) support, instead there will be a new format of an unknown name and capacity which the FAQ section says will be "a small flash memory based card." That means it will be possible to store save games directly on the card, as well as additional game content data. Sony also clarified the compatibility issue - there are no plans on making PS Vita compatible with PS2 and PS3, though it will be possible to play PSP titles, minis and PSone classics.

No 3D, no gaming on the TV

Nintendo decided to feature the stereoscopic 3D technology (glasses-free) in its newest handheld console Nintendo 3DS, but Sony studied the glasses-free 3D technology and decided not to install it, focusing on the features and spec instead.

PS Vita does not support HDMI or video output in any form. That means it won't be possible to play games on bigger screen in contrast to PSP 3004, which supports video out.
