If you want more new games out NOW, choose 360
If you want to retain the ability to play your PS,PS2 games choose PS3 (80 gb mgs4 bundle of course. the 40gb is a rip-off!)
Also, pure exclusives are a thing of the past so any console will do if you have patience and the timed releases may not even release at full price when launched on ps3. If you can't wait get a 360. If you can wait, delve into ps2/ps1 gems and have fun while you wait.
JRPG-wise, if you have a wii, I'll assume you are not graphics-biased so I can guarantee that there are tons of excellent games that are on PS/PS2 that are much better than the newly announced "nex-gen" JRPGs. Also, Persona 4 is probably going to be one of the best JRPGs when it releases. Hint: Its a PS2 game. Note that this post assumes that your PS2 is broken since you described it in past tense.
For example, I myself just beat mgs4 and am now currently playing legend of dragood (ps1 game!)

"WAR is a racket. It always has been.
It is possibly the oldest, easily the most profitable, surely the most vicious. It is the only one international in scope. It is the only one in which the profits are reckoned in dollars and the losses in lives"---Maj. Gen. Smedley Butler
