Well it's not confirmed, but I think it's safe to assume that the inclusion of a motor is going to affect the look of the model. Hopefully it won't though ;-)
Yes, set 10178 will be a waling AT-AT. But don't expect it to be as good as the last AT-AT (4483), this one's looks have been partially sacrificed for the walking feature ;-)
I decided I'd give him 3 (I contacted him via PM) to make it fairer to other members. He still wants 5, so if we don't get any more tickets sold (unlikely), we can increase the total to 5.
Actually, the 5 gold C3P0s can only be won in an online competition coming up later this year. The ones that will be included in boxes are just chrome ;-)
Perhaps LEGO will use the mold from the AT-ST pilot and give us a General Veers!
And I don't think that the AT-AT is as bad as everybody says. The head could be better and the body is a bit boring, but overall it's a pretty decent size and is quite accurate. I won't be getting it (I have 4483), but it's alright :-P
It will most likely look similar to this prototype from the poll last year:

EDIT: And n, it's not confirmed, but I can try to get it confirmed.
There was a rumoured 10178 Eiffel Tower set, but it looks like that might not be true.
And by the way, just because something's not listed on Brickset doesn't mean it's not real. They don't tend to list sets until they're confirmed ;-)
