I have 2Gb free on my 60Gb PS3.

Now, I know that 320Gb 2.5inch HDDs are cheap nowadays, I was shown a PS3 friendly one for just $100, and I plan to get that later this Winter so that I won't have this problem ever (don't see myself filling that sucker up!).

Until then, I'm deleting a lot of demos and stuff. I'm gonna get it down to 5Gb free, hopefully that's enough.

Better to do the deleting NOW, rather than when I see WO:HD on PSN and then panic and go about deleting stuff when I could be playing the game.
