Okay, obviously this version is better than the 1980 mold. But in my opinion, not all that much.
I still am leaning towards not picking this up. The head is too big, the body is too small, despite this version being taller and bigger than the last one. It's bigger, yes, but the problem of proportion still persists.
While I'm glad to see some euphoria in the hobby for this, I don't think it's good enough for my $100. And quite frankly, this is the worst Toy Fair I've seen. There doesn't seem to be a particularly great lineup of figures, and not all that much of them. I can't think of anything Star Wars that I want to buy right now. I remember 2007 at this time of the year, I was drooling over the 30 AC offerings, hunting every day for Galactic Marines and Airborne Troopers.
There isn't anything to be out and about looking for, for the next half a year at least except Marvel figures. Toy Fair was very disappointing.
At any rate, yeah this AT-AT looks a little better, but when you look at a picture of the AT-AT from the movie, then at the toy again, it just doesn't measure up guys.

Look at the picture. Now look at this
video of the new AT-AT toy. Then look at the picture again. That head is huge! The head:body ratio is still bad. The back had to open up to launch a speederbike though, that they can do. But getting the most important sculpt proportion even remotely close, nope too hard.
