What Would Drive you to the other Consoles?

[BreakABone]

I think the thread title says it all.

But speaking to Stu about getting a PS3 (because I feel the MGS 4 bundle is too good a deal to pass up) but outside of that and Uncharted there really isn't anything I want on the console, which is why I have never pulled the trigger (contrary to popular belief about me only supporting Nintendo )

So curious since I don't think many tri-console owners here, what would make you want to get the other one or two consoles you don't currently own. Price drops? Huge must own game? New bundle?
