I havn't really seen the point in purchasing a PS3 sofar since they have a week online setup & in my opinion there title range is it's very poor!
Infact every game worth obtaining on ps3 is already available on the 360

I'm a big fan of the Metal Gear Solid series - I fuckin loved it on the ps
& MGS was always for me the contendor that brings the ps3 up for serious concideration.
After watching this video my mind is almost made up...
Metal Gear Solid 4 - Guns of Patriots : English
http://www.gametrailers.com/player/31703.html
The game looks very deep & intricate - I particulay like the mix of 1st & 3rd person play, along with what seems to be very detailed character control and a plethora of weapons & gadgets
I would be completly sold if it had online in both co-op & team deathmatch style play.
