Actually, I only own a DS... but I'll have a PS3 next month so I won't include it.
X360:
Halo 3: I like the Halo universe, multiplayer is severely badass. Very good shooter.
Lost Odyssey: I very much how it looks. I also heard it's similar to FF X, how can you not like a game that's similar to FF X?
ToV: Best JRPG this gen yet... I bought it for my friend as a b-day present.
Star Ocean 4: Looks terrific, free space travel, badass battle system, it'll probably be the 360's best JRPG.
Mass Effect: Well, the only WRPG's I like are the ones from Bioware. Plus, from what I heard, it's a very good game.
Wii:
Nintendo FP, because I very much like Mario, Metroid, and Zelda.
No More Heroes: terrific art style, loveable hero, it's just a pleasure to look at.
Fragile: A JRPG in a dying, ruined world, with horror elements and anime? do want...
ToS 2: I like the first. I want to know what's after (well, still haven't finished 1, but still)... 6.7? won't stop a JRPG fan. They are almost never well received in the west, and therefore reviews are not to be taken very seriously.
Sin and Punishment 2: I saw a trailer, it looks incredibly fun and badass...
