Went to Target today and got to play the PS3. No line to play. Then again, it was NBA 07.
The thing has amazing graphics. Slightly better than the 360. The downside is, everything felt like I was playing a PS2. I didn't get to check out the menu screen, so I was missing out on that. But the gameplay was almost too similar to PS2. Although, since there was next to no change in the controller shape or button layout, it was easy to just grab it and play.
My Target had 8 PS3's in stock, and there were only about 10 in line. I went there at 9:30, about 10 hours and 30 minutes before the release.
My Best Buy and Walmart both had lines of about 40 or 50.
