If I'm not mistaken there will be four movies. 3 of which will be slightly different retelling and the final will be 'totally different' ending. Well that's according to a source I read not long ago.

Anyway I agree 2.0 is much better than the first. Bloody intense towards the end. Epic fights. The only thing that spoilt it for me is one snobbish otaku sitting 2 chairs away from me making loud comments to the fren throughout the show. It's people like this who give the rest of us anime-loving ppl a bad name!
