Unless a bunch of exclusive JRPGs come along that are 70+ metacritic then I will not be buying one.
I'm not interested in watered down console ports or quirky original puzzley type games that the Vita is currently receiving. I've played those quirky games on my PSP and good as they are, they aren't worth the investment on the Vita in different forms imo.
I don't really see a market for the Vita at the current time with it's current lineup of games, for me at least. I also doubt if long term support can be maintained. That situation will be clearer Q1 2013.
