PS2 or the 80 GB MGS4 bundle (assuming you are in the US). There are so many PS2 games you've missed. I think I have bought more PS2 games in the last year and a half than PS3/Wii/PC combined. Plus you can usually buy 3 or 4 for the price of one new game. Also did you have a PS1? It seems that you like JRPG's, and there are a lot for it that are worth a play even today.
If you are buying it solely for current gen games (that are out now): 360
If you have a gaming PC: PS3
If you want to watch blu-ray movies: PS3
Well I could go on with different pros and cons, but I'll just end it here. I could also recommend some more PS2 games lol.
