Shin Megami Tensei. Persona 3 FES on PS2 is the highest rated JRPG to be released on a console so far this year and part 4 coming to PS2 this holiday season is going to be even better. Your best bet right now for rpgs is to get a DS for some of the classic rpgs from Square, a psp for the more cutting edge rpgs like Final Fantasy XIII Agito that are on their way to that handheld, and a PS2 for its back catalogue of rpgs (it will also allow you to play the PS1 rpg classics as well. The PS1, SNES, and PS2 are the three systems that have had by far the strongest catalogues of rpg games) particularly the ones from Square, NIS, Level 5, Atlus, and Working Designs (PS1 versions of Lunar 1 and 2 and Arc the Lad Collection) that are better than any jrpgs that are on or will be coming to the 360 or Wii in the foreseeable future, then get a PS3 when the blu-ray version of Final Fantasy XIII comes out here in the US.
My most anticipated games: Whatever Hideo Kojima is going to do next, Final Fantasy XIII, Final Fantasy Versus XIII, Gran Turismo 5, Alan Wake, Wii Sports Resort. Cave Story Wiiware.
