I'm holding off on that decision until the first footage starts to emerge, trailers etc that will give a sense of the actual film itself.
I generally don't go to 3D versions of films (I think the last time I did was 2010 when I saw Avatar for the final time) and prefer the 2D.
Depends how many times I may want to see the film as well. If it was more than once I could do a 3D comp but would probably go to the 2D first.
