I'd love a PS3 and I'm positive at some point I will purchase one, but $600 is outrageous to me. I just can't see myself wanting it bad enough to fork out that kind of cash. Seeing as I have a pretty powerful video card, computer games will have to suffice for now. In all honestly I don't game that much anymore though, eventhough I'll always love it.
I also think the new systems are a waste of time if you don't have an HD-TV, which really takes advantage of it. Who cares how powerful the system if if you have to run at horrible TV resolutions? I won't be purchasing a PS3 until I get a HD-TV (unless I can run it on my 21" LCD monitor somehow).
