Eh, I'm not too fussed about Sony's announcements. Lest we forget that E3 last year was a bomb too, but Gamescom had a pretty decent showing (Killzone + Tearaway, decent in my mind).
I became content with my Vita purchase a very long time ago. I bought it to play WipEout + LittleBigPlanet + Gravity Rush + PSP games with dual analogue since I never owned a PSP. It has achieved every one of those goals.
Sure, it'd be nice for it to have a brighter future. Lately it's been home to all sort of platformer announcements (Tearaway; Jak Trilogy; Rayman) and, as that's undoubtedly my favourite genre of games, just makes me even more happy. JRPG's (my second favourite genre) I think have a pretty decent showing too, and with Shahid's recent burst of interest I expect more in the future. I'm kind of enjoying having a portable PS2 too, in a roundabout way. I'd rather have ports of HD Collections than no-effort rubbish like Blops Declassified.
Could've been much better, sure, and I understand everyone's disappointment. But it is what it is, and what it is is more than good enough for me!
