Rumours of a bigger Vita sneak out of Japan

IIt didn't take long for Nintendo to shove an XL on the original 3DS. So should we be surprised that Sony might be sneaking out a larger-screen Vita?

Reports from a Japanese newspaper (Tokyo Keizai, which appears to be a university, making the story sound a bit fishy) suggest a PCH-2000 model will come restyled to match the PS4, sporting a 6.3″ OLED but at the same resolution and with 1 GB of system RAM. Surely they could squeeze full HD into that without upsetting the applecart?

The extra memory will let more programs multitask, but won't be accessible to games to preserve BW compatibility. The question is, besides what's the point, is will it include some internal storage or support for cheaper memory cards? That'd be nice, along with decent speakers which are appearing in phones and tablets now.

The Vita is already plenty big and users are asking for HD-out, not a larger model. The idea might appeal to Japan, but is part of their insane, must have every colour/size/shape culture. The west won't bat an eyelid, unless perhaps it offers full Android and acts as a phablet too.

A reveal, if true was slated for TGS, but if the leaks prove true, why wait for such an inconsequential announcement. Any name suggestions? PSV-Go, PSV-Stay, PSV-Wideboy?
