Yeah Japan is almost settled now (until the lull then sudden spike that is Golden week)
All three home consoles will likely drop a bit more (Wii into the 60-70ks, PS3 to around 15-18k, 360 about 3-4k) in the coming weeks, ignoring any important releases.
I really don't know where the handhelds will go, DS may stay steady and keep below the Wii for a while, PSP I think is declining from some important games released in the holidays and the last two weeks, but it might still keep up with DS (DS 55-65k, PSP 50-60k)
