As I said, I just read that somewhere. It's seems from what you say, that they were able to salvage some code. It would not surprise me if all art assets could be carried over no problem, since they even reskinned a crucible map to bring it into D2. This doesn't help D2's case as to why they're missing so many features (not even content)... the quality of life stuff that makes playing the game more fun. (like custom PVP games are missing... no excuse. Not that I care about PVP, but really, that was a universally loved feature, as far as I can tell.)
