The main reason we will never have animations like 1.0 is because 1.0's cutscenes were mo-capped. They were AMAZINGLY well done and animated, but that also brings an extra cost, and I don't think they'll ever justify being able to spend extra to do that again.

1.0 was a really weird mess where there was a lot of stuff not done in MMOs before or since. Mo-capped cutscenes, intensive crafting that required you to make the mats for EVERYTHING, the game knowing where you were on a sloped surface and adjusting your stance, inertia when running/stopping, seemless regions with no loading between city and zone (except between different regions), etc. But a lot of that while nice was also a lot extra that was deemed unnecessary and trimmed off and I don't think we're ever getting it back. 1.0 spent a lot of money and effort on inconsequential things while ignoring much more important stuff, like maps with things in them and a playable game.

That said, I think it would be nice to bring it up to Yoshi-P at a fan fest or something.
