I think the rest of this month is just portables. This week, there's Ace Combat X, Spectral Vs. Generation, and Shinobido for PSP, and also Gyakuten Saiban 2 and Lode Runner for the DS. JoJo's for PS2 is out thursday too, but I want to wait and see what others think about it first.
I can't think of too much else coming out that I'm really anticipating for the current systems (not counting 360 since most games are released in the U.S.) other than some more portable titles like Metal Gear Portable Ops and Castlevania. I think most of the focus is going to be on Wii and PS3 stuff, but I always tend to forget about so much.
Recent releases I haven't seen mentioned here that have been fun are Gundam Battle Royale on PSP, Gunpey for DS, and very little has been mentioned of Minna No Tennis around here.
