Got a few games on 360 i'm still playing through & on Wii i've recently picked up Disaster (looks good) & No More Heroes (Class!!)
Of the 1st quarter releases i think only MadWorld & Resi 5 (360) will be first day purchases, i like to take my time with games i enjoy & prefer quality over quantity.
Of the other Wii releases i will probably pick up eventually, not on day 1, Monster Hunter 3, the conduit, Pro Evo 09 & HOTD Overkill. Don't know about Dead Rising as i have it on 360 & will see what Moto GP Wii is like if it ever comes out.
