I'm as interested in seeing the playground locations. The last NBA game I played was NBA2K2 and I played it almost entirely in streetball mode. I'm a little worried. That first location in the video evokes NYC architecture, but the court itself looks like an amalgamation of Rucker and the Cage. Hopefully it's just a different location.
Those two are a must, and 16th and Susquehanna in Philadelphia would be a huge bonus. I'm a little hopeful for the latter, because I saw an image online (can't remember if it's in the trailer) of Wilt in his old Philadelphia Warriors uniform. I also recognized what might be Venice Beach, but I've never been to that court. Another image looks like it has the London Eye in the background, which after googling, I suspect is from the Nike Court on the River Thames.
