PS3's are the better investment for the future. It will eventually own 360. Sure it has some good hits now but it still isn't on 360's level. It'll get better then 360 in the future.
360's are where its at CURRENTLY, its practically at its peak and owning PS3. It'll probably lose its thunder by 2010 or late 2009.
Wii is in its on world, they fucking rock and everybody enjoys it, even PS360 fanboys.
My best way to put it since i'm PsWii60 owner.
Edit- And will people please stop using the logic of rrod makes 360 sucks, and overheating makes ps3 suck.
If we're gonna use that logic, then I guess Wii is better then both because it practicallly has no problems whatsoever.
These 3 systems all rock, plain and simple.
