Today I went to this store where they had a bunch of demo 'fake' Vita models that are basically the real plastic outside but impossible to turn on/off, and with a sticker on the screen. Anyway, I played with it a bit, pressing the buttons and all that, and they felt great.. but the analog sticks are damn small. Like, really.. if you think about it for a second and look at the pics you will realize it, but they are barely about twice the size of the normal buttons, and that's quite small. Other than that, the screen was huge and overall felt 'expensive' and well done, almost like the Apple hardware.
The only thing I'm not 100% sure about are the analog sticks anyway, the 3DS slide pad felt better, but then again I only 'tried' them for like a minute.
3DS slide pad did not feel better to me.
Maybe they have reasons, remember the E3 05 fiasco
I'd rather have CG videos of games coming years later than logos and a whole lot of nothing.
