The best and not the most? So far WKC and FFXIII, FFVXIII look going to be the best so I go with PS3. But a lot can change though.

wiis seems to be getting a lot of JRPGS from marvellous and namco, but so far its just those companies. however nintendo looks like itwill also start offering a numbe rof RPG titles. however expety msot WRPGs to go to 360 not wii. PS3 will get a mixture of both

Console - The SONY Playstation 3 Computer Entertainment System

Handhelds - The Nintendo DS now, and the PSP in the future.... errr.... [However it's a good idea to have both handhelds since they will both have some amazing JRPG's]

well if we take out all the hype around ps360 games i would say wii.

most(if not all) released and upcoming hd jrpgs are average jrpgs with shiny shiny graphics and well known name, but without anything that would not only blow my mind away, but let them stand out from hundreds of other jrpgs on psx/ps2 i played.

wii will get kizuna, rune factory, inazuma eleven, fragile and other not so ordinary jrpgs while ps360 is still getting mostly nothing-new-with-nice-graphics jrpgs.

and lol at War Devil cuz it is tpp action game not a jrpg.

Why the PSP in the future?

The DS isn't a console... but it wins anyway.

xbox 360

Both handhelds will receive incredible RPG supports from SE and level 5 in 2009.  Even though DQ IX will trump everything in Japan, I am really excited to see Level 5 trying something new like Ushiro on PSP.  Horror RPG, how cool is that?

PSP
SE: Kingdom Hearts Birth by Sleep; Parasite Eve: The 3rd Birthday; FF XIII Agito
Level 5: Danboru Senki; Ushiro


DS
SE: DQ IX; Kingdom Hearts 358/2 days; FF Echoes of Time
Level 5: Inazuma Eleven 2; Ninokuni: The Another World

i mean consoles manuelf :p

Star Ocean The Last Hope hardly plays the exact same then the previous SO games.  It may have the same basic battle system but it also has a new ship, a new PA system, a sight in/out system in the battles, and is probably going to be less linear.
