One person has stated in the WoT FB group that since they haven't already begun filming it CAN'T be out next year, but I don't think it a given that no filming has begun just because everyone in the fan base hasn't heard about it yet. A Christmas release still seems possible even then; TLotR, HP, and Narnia may have convinced Hollywood that fantasy films MUST be released ONLY at Christmas. What they've definitely done, however, is convince Hollywood that very popular fantasy series can be cash cows, and that was really all that held back the flood of fantasy movies we can expect now. Since WoT hype will only build in the months leading up to AMoL I think it's a question of if, not when. Best format would probably be to try and double up each book; even then we're looking at seven feature films, but I don't see any way to do fourteen; the actors would age too much to be convincing in a story that spans about two years.
