Why would it cost them double to make a better battery? Theres accessories for the 3DS that already prolong its life by a huge margin that doesn't take up a lot of space. So to me its just poor decision making...

I also cannot take any fighting game that seriously on a handheld. Thats just me though, I play them competitively and arcades are really the only way to go...and if theres an offline version its only for training room and I need to use a joystick or it might be bad when its competition time. So the handhelds are a huge waste of time for me. Similarly i can't play FPS on a handheld and i don't understand why anyone would on a handheld and not a PC or at least a console. So in many ways i don't see whats the big draw for the Vita.

I need something unique and special for my handheld, or its not going to garner much interest...

RPGs though i am fine. Those are just fine on handhelds, the change to portable from console/pc isnt that huge. But if you are always moving then of course handhelds are going to be awesome.
