Head sounds possible since Oscar Scherlin is no longer skiing for them (Volkl now) and Jon Olsson is not involed in the freeski scene as much as he used to be.
I've also heard a lot of things about Simon signing with CoreUPT but I don't think this will happen.. They already sign JF Houle and Kevin Rolland this season, adding these two guys to the rest of the impressive time, that's already such a big and expensive team to manage.
Eitherway, my guess would be Head, Kastle, Scott (since Lolo Favre is not on the team anymore) and maybe K2..
