Sorry it took me all day guys I was playing until I had to go to work but now I am home, so I will answer the questions that don't require me to go on and check things, considering I can't turn my ps3 on right now.
dreadd41: They call certain players by there numbers, its sad but I understand they can't have someone saying everyones name in the game. and the Arena announcer says full names.
joejam999: The graphics are just fine I don't know why they are like that on the demo, but everything on the court is great, the fans are great, the arena's look great.
ConfigSys: there are no stat overlay's during the game, I realized that earlier and it's bothering me. I haven't seen any at all through about 10 games unless I AM shooting free throws.
Sportsgamer: Don't know about the be a pro mode, didn't realize they had it last year? But isomotion is alot harder to control now and the moves do truly pay off, but sometimes they are unresponsive.
cyanide: The gameplay is a lot better than 2k8's I honestly didn't expect such an improvement, I just love the overall look and feel of this game.
Big green: Don't know about the teams but the blacktop mode is there, haven't gotten around to trying it yet.
JWL3: Yes the gameplay is great, I can't watch the trailer my computer is to slow, but this game is nothing short of amazing, you can control what your player does and you can string them together for a bunch of awesome plays.
