My guess is it's trying to appeal to 2K players, as it reminds me of a video game. I've not played 2K, but I've seen some of the NBA 2K League game play and they have angles like that. I also imagine that akin to innovations like the camera that swings low above the football field and the imaginary line that marks first downs, the 3D will be soon be ubiquitous to every game and we won't be able to watch a game without it!
