There were meant to be some revisions to the Bone system for the animation side of things.. such as a timeline so you can drag a slider back and forth to see how the keyframes look during tweening.
This would help a great deal in perfecting the movement of various things, like legs for a walking animation... body "bob" and more natural looking movement in general.
Currently as you know, the result tends to yield a strange "skating" or "floating" look when you animate legs/walking in particular. If you have a reasonably good grasp on how animation works you can usually mess with it enough to get a good result, but as UberLou said it tends to lend itself to being a pain in the butt.
I have recently started playing with bone animated characters again... and I for one welcome the proposed revisions.
Having said all of that, the fact that a bone system even exists is fantastic. Without it, we would be limited to old-fashioned animating, or having to learn some freakish math to make IK solvers and stuff like that.
Nothing wrong with being wishful as long as you are grateful as well.
