I don't think we will be seeing any Wii game there for a long time now. It's getting only 5 new games in the next three months, and none of them is relevant besides Metroid: Other M, which isn't that big in Japan either.

PS3 on the other hand is getting 33 new releases (5 are re-releases though), so we shall be seeing an infulx of PS3 games in the near future.

360 has nothing relevant besides Reach.

concerned about GT5

Pokemon still having good increment in preorders

Yeah well Nintendo are keeping the big guns for the holidays like they usually do. PS3 though looks like it doesnt have that killer game for the holidays (yes i dont think GT5 will be killer but rather solid)

GT5 will be a killer game!

PSP is on fire in japan. 9 titles!

Pokémon is still the king though Monster Hunter is a great runner-up XD

Kirby's "fall" in Japan, so it should release before October... and honestly, Kirby will probably outsell every PS3 game on the list.  Nintendo's lineup should become clearer after their fall conference, likely just after TGS.  Remember, games like Wii Party and DQMBRV were only announced less than 3 months before they hit shelves.

Also, Wii has six new games scheduled so far (Tetris Party Premium, Twinkle Queen, Metroid OM, Deca Sports 3, NMH2, Active Life Explorer), and 3 reprints (Okami, RE4, REUC).  None will be big sellers though, Metroid's the only with a chance to break 200k imo (or even 100k, lol).  PS3 has 31 new games for the same period, but over half are western titles (like Madden, RDR, Singularity, etc), one's an online upgrade pack (for Nobunga no Yabou) and the only potential 200k plus seller in the mix is probably ACE R.  PS3 should fill out more too though, I'd expect GT5 in October.  360 has 23 new games in the same period, again about half being western and one online upgrade pack (for Monster Hunter Frontier).  No potential 200k sellers there though.

I was basing myself off dengeki for the releases, perhaps they are missing some, but clearly the Wii line-up is depressing, 6 games in 3 months with none being relevant... (When is Deca Sports 3 coming out?)

PS3 has some potentially big selleres (more than 200k) until the end of October, like ACE:R, PS Move and Macross Trial Frontier (bundled with the movie).
Dead Rising 2, RE5 Gold Edition, Front Mission Evolved, Mindjack, Naruto Ultimate Ninja Storm 2 and some of the Move games should all sell in the 100k-200k range.
There's some games that are wildcards like Neptune, Trinity Zill O'll, Class of Heroes 3, Quantum Theory, Red Dead Redemption, EyePet, Vanquish and Agarest Senki 2. They could reach 100k sold.

For the Wii I only have Metroid: Other M selling an upwards of 200k, the rest is too small, NMH2 has the distant chance of selling well, but I won't bet on that happening. As for Kirby, Fall ends in December, so it could easily be a Nov/Dec title.

wow pokemon to soon overtake mh3p O_o
