I don't believe the new box for Termagants personally. And did I read right they were infering it would be a duel kit with genestealers or am I just msisreading things in my lack of sleep?
I can see Necrons, Grey Knights, Space Wolves, Blood Angels and Dark Eldar as being especially vey easy to update after all the support they got in the previous edition (I imagine all of those will likely be the last ones to get codices...).
Not sure how I feel about IG, I think they should have smaller/better infantry plastics to put them in scale (not to mention I find cadians and catachans to be pretty ugly) but i guess that is more bias on my part.
