Eh, I don't think the failure of this film really says much about the future of 3D. The title is extremely off-putting and unattractive. I didn't know it was coming out and I frequent enough genre websites to be pretty aware of what releases are on the horizon.
The idea that this movie's failure would cause studios to rethink the use of 3D strikes me as wishful thinking on the part of those who don't like 3D. I don't have any special attachment to it either, for the record, but I don't expect it to disappear anytime soon. For that to happen it would have to become clear that making a movie in 3D hurts the bottom line more than it helps, which I doubt is the case for the time being.
