I've been debating whether to post this or not, but I may as well. This is what I've heard is coming in terms of kits:
New Avatar sculpt
New Falcon variants
Entirely new vehicle
New jetbikes and vyper jetbike models
New character sculpts, new special character(s) and new SC sculpts
New versions of Aspect warriors, similar to current models but 'more dynamic'
That is everything, no more details than that, source has been semi-reliable but I've not been able to corroborate this with any reliable rumourmongers as yet.
