The klickies (and acessories) surely will be very interesting, but with regard to buildings I first want to see what they come up with before getting really excited...
I'm interested in what, if any, buildings they do, mostly because I don't think any of them are more central than the others.
Perhaps, in order;
The Roman Fort (I'd suspect it would be minimal, so maybe the gatehouse and some walls/towers and a couple of tents)
Asterix's House - is very similar to the A-Frame holiday houses they've made
Cacofonix's house - a minor character but he has the most fun house
I wonder if they would make the pirates? I know they're supporting characters but recurring, and they always like a boat.
I'd like to see the big round table for the feasts at the end, and I guess we'll see roasted wild boars. The wild boars in the books are grey, which I think will be new
