As long as you can upgrade the system at a later date, I'll buy the 20GB. I don't see needing a 60GB, but if I do, I'd like to just do a switch out.
$500 seems about right on with most speculation. I think a lot of people were hoping for lower though. If it was $300 - $400 at most - Sony would probably have the upper hand this year.
I still wanna get one at launch, but I'm concerned that I'll be supporting a trend and telling game companies it's OK to keep going higher and higher with prices. I don't want the PS4 to be $700 or something.
