Usually, there isn't much discussion of individual fiscal quarters outside of the holidays, but Q1 2010 has a lineup that surpasses any holiday season for the past several years, and many other highly anticipated games are coming afterwards. So, this thread is dedicated to every (important) title releasing in Q1 2010- which includes sales predictions, scores/ratings, and a host of other things. So to get it started, here are several titles, more of which will be added as time passes.

Red Steel 2 (Wii)

Bayonetta (PS3/360)

Bioshock 2 (360/PS3)

God of War 3 (PS3)

Mafia 2 (PS3/360)

Also, as for other releases in other platforms in Q1 2010, you didn't mention:
Singularity
R.U.S.E.
I Am Alive

Now imagine if the new Zelda came out in 2010. With new iterations in the main series of Max Payne, Final Fantasy, God of War, Zelda, Metroid and Mario, this would the most epic of all time!

I REALLY need more info on I am Alive!!

I Am Alive has got such a great and original idea for story and setting, but I'm trying to hold back my expectations since it's made by Ubisoft Shanghai who are very inexperienced.

You never know, they might surprise everyone.
