I'm considering a Vita again because it's on sale for $199.99 right now with a 4 GB memory card and a game I will probably sell and Persona 4 Golden is on sale as well for $29.99 right now. One problem is, I would like to get caught up on the PSP library that I missed out on as well, but most of the games I would want aren't even on the PSN Store like Kingdom Hearts: Birth By Sleep, Crisis Core: Final Fantasy VII, the Star Oceans, and Metal Gear Ac!d 2 (there may be others that I'm forgetting). Also, I'm a huge JRPG fan so having the PSOne Classics playable on the Vita is nice as well as the other JRPG's on it or coming to it, but the PSP can also play those PSOne Classics. So based on that, I'm not sure if it's worth getting a Vita or maybe I should just get a PSP. Or maybe I should wait until E3 to see what Sony has planned for the Vita.
One thing is for sure, if Tales of Innocence R and/or Tales of Hearts R were to get localized to NA, then I would buy a Vita in a heartbeat. I get every system that Tales games release on (in North America).
