I love everything Ive played from valve, I could say Im a valve whore and really love their ways of doings business and their products. The orange box was or is one of the best games Ive purchased even if EA did a bad port I loved every second. Having said this Im always reading rumors and forums trying to find any note about l4d and the ps3, I have a computer capable of running l4d but I really enjoy playing this kind of games on my ps3 with my friends and really I have been waiting for valve or EA to bring l4d to the ps3.
The thing is left 4 dead is a new franchise even for valve and rumor has it EA didnt want to take a risk in porting left 4 dead until it had proven to be a granted success, but the truth is left 4 dead has had little to no negative reviews all over the place and people praise this game.
EA ported a huge game with the orange box and some of the good news is the source engine has already been ported by them and paper work to bring the orange box has been done in the past. So left 4 dead has proven to be a success, the source engine wont be a problem for the ps3, the momentum is here and even valve has agreed that maybe a port could come to the ps3 if someone was interesed in doing it (Hinting at EA).
How difficult could it be for EA to port now l4d with help of valve? I think it could be pretty easy and fast to do it and by fast I mean a couple of months of work and could mean a quick buck for EA and Valve. Anyway ill take that preorder card with a grain of salt but the truth is sooner or later we will get left 4 dead in the ps3.
