There's confirmation that the Hobbit will be done in 3D as well.
3D at this stage is just too gimmicky for me, but everyone wants to do it now because Avatar made so much money
I'm fairly disappointed to hear that about the Hobbit. Smaug might be kind of neat in 3d though. I really can't wait to see the battle of the 5 armies. I hope they don't leave Beorn like they did Tom Bombadil.
