Not really sure what you mean by the Heavy Weapons part.
Just going on the basic structure of the new starters. They seem to include a couple of small 5-man units of basic infantry (Undead Legionnaires, Chasseur, Troopers, Hussar, etc.), a character (sometimes named, sometimes generic) and some kind of heavy unit (usually a battle-suit or a big monster, like a Razide). There is a little room for play in here (Cyber's character is actually larger than their "heavy" for example) but it seems like a good method for predicting/wishlisting.
Speaking of Imperial walkers, I'm interested to see how they remake the Hurricane and whether they keep it as a goofy airplane ****pit on legs (complete with stubby t-rex wings) or if they attempt to make it look a little more non-silly. The cover art for Casualties of War makes it at least a little tricky to do a 100% remake, because it actually doesn't look horrible in that picture (and the rest of the piece is quite good as well). But it just never seems to look as good as a mini as it ever does in the art. It may just need a minor tweak though (like changing the mini-wings in to proper weapon housings).
