I heard that WB wasn't going to release the 3D version of The Deathly Hallows part 1. Is this going to be the same for part 2?

I'm not sure. I guess we'll be sure when it's closer to July 15, 2011, the jour of its release

Part 2 will be in 3D because they will have it ready in time. It will be crappy though since they are converting it into 3D (which is considered crappy 3D par the film industry) rather than having shot the whole movie in 3D (which is considered good 3D).
