Let's not worry about price for a second:
I still can't make up my mind about digital vs. retail. I want to support digital because of it's immediacy, less wasted plastic, the possibility to re-download, keep all games with me on the go, etc.
But I can't help envisioning myself in 10-20 years turning on my Vita to play, seeing something has gone wrong with the mem card or something, and not being able to get to my games ever again.
Just this weekend I found a really cheap copy of Chrono Trigger at a garage sale, took it home and popped it into my SNES and played. Then took out a handful of othe SNES games and played. No dicking with accounts. No connecting to some server to validate my purchase.
Shouldn't we expect physical vita carts to operate the same in 20 years as they do today? I have no idea if/how/why Sony would support Vita digital downloads in 20 years, and that shit worries me.
