Im very happy with a PS3. I like MGS, FF, and GT.

overall man, it really comes down to few things

what games do you like and want and how much are you wiling to give up for that?

I'd go 360, your gunna have a huge range of fps, WRPG's, a few great JRPG's, action adventure, RTS, ext. MS has the spending power to have a flow of AAA games. I would suggest buying the full 3 year warrany, which pushes the 3 red ligh warranty to 5 years with MS, thats what i did.
i had 2 make that decision too when i only had a wii, and i couldnt be happier.

360 because wii has alot of the same genre of games that the ps3 does and the 360 would give you the ultamite collection of shooting, RPG, Puzzle, Racing, etc.

Get the ps3.

Uncharted

R&c

resistance

heavenly sword

You will be in love with the system(warhawk) seriously best $600.00I ever wasted.

I love nintendo (the wii not so much), ps3 is best for nintendo fans. story driven epics, action titles, king of rpg?s, reliability, platformers, shooters, fighting king (tekken), mature games, everyone games, free online, quirky titles, cinematic adventures, blu ray etc. Nintendo would even suggest ps3.

LOL best 600 bucks ever wasted? Finally we get the truth from leo j

Simple! Get the 360 now - well, in couple of weeks.
Start saving money to buy PS3 next year November!
Problem solved! Have fun.

Since you seem to want a new system now buy a 360, the PS3 blockbusters won't be comming out till next year and hey buy that point maybe you'll want a 3rd system.
