Well since the subject in the OP is dead, let's discuss something more important.
What's taking so long for them to spit out a Vita phone and Vita tablet? We have to be getting to the point where the Vitas internal guts can be stuffed into a modern smartphone shell.
Look at the newly launched Xperia Z Ultra as a perfect example. It's got the uber powerful S800 processor, 2 gigs of RAM, a 3000mAh battery and a 6.4" 1080p display, and it's just 6.5mm thick. Vita has a less advanced processor, 512 megs of RAM, 128 megs of VRAM, a 2200mAh battery, a 960xx544 screen, and it's 18.6mm thick.
Of course I won't deny that one is an EXTREMELY high end smartphone that commands a premium price, and the other is supposed to be a mainstream gaming device sold at a much lower price. Even still, it just shows how much they can stuff into a far thinner form factor if they put their minds to it. If they decided to build a Vita phone it could be extremely thin (compared to Vita itself), have a larger battery and would likely be quite popular. A Vita tablet could be amazing as well if they use the Xperia Tablet Z as a starting point at just 6.9mm thick.
I dunno... just hoping that such devices are being worked on over at Sony and that they'll see the light of day in the next year. Also, still hopeful they can one day dual boot Vita OS and Android. Make it happen Kaz! I believe in you!
