Well, assuming that we're gonna be dealing with more space themed objects this year (like the remote control from Overdrive relating to controling space probes or the regolith being like the surface of the moon) I think we'll either be stuck with less traction/less mobility or we'll be using an entirely new method of control as an option (e.g. IR remote). And as for the field that would be an interesting idea for a field and I'm not gonna say the GDC will count that out, so yes morphed surfaces would make it challenging.
Also if what I've heard is true they found water on the moon so ice may be within the means of terrain and what best represents ice but the regolith from last year?
