Ho boy, now we have the other consoles being brought in to a PS3 thread .
The 360 has plenty of fun exclusives out there, and some upcoming ones like Mass Effect, and Blue Dragon. But more importantly, when given a choice between a PS3 version and a 360 version of the game, so far the PS3 just doesn't have something as good as achievements, which push you to go that extra step to doing something more in a game, or even finishing it. In addition, the 360 is cheaper than the PS3 for what appears to be generally a similar lineup. For what it's worth, so far the PS3 just has the weakest set of exclusives coming up, even when compared to the Wii. What's coming out in '07 for the PS3 that'll be on par with Metroid Prime 3, Super Mario Galaxy, or Smash Bros. Brawl for fun? Or even for the 360's offerings? It's looking rather bleak this holiday, and this is coming from a PS3 owner.
The only thing that seems worth buying a PS3 for is its own exclusives, and it is sorely lacking in that department now and for the near future.
Also about the return rate, a survey is a poor substitute for actual data. It said up to 33%, not mostly.
