First and Foremost is White Knight Chronicles for me, its Day 1 no matter what, now that i know for sure the Create-A-Character is Vast and wonderful looking, creativity will explode with awesome-sauce when i get my hands on this game...
BioShock 2, since the original was so... ORIGINAL, day 1 forsure but only due to Online Multiplayer.
Conviction cause the main character is Man pretty.
Last Rebellion but only after legit reviews come in and after i judge it by my self then i'll get it, so not day 1 for this one even IF it looks alot like Chaos Legion.
And as for SO4: the last hope, no, i've played the hell out of it on Xbox 360 already, and unless they add NEW playable characters for the PS3 version i will most likely wait SO4 out on PS3 til end year 2010.
