Where are all the ice skates, snowshoes, sleds, sleighs, snowmobiles and skies?

A snowboarding gate would be insanely fun.

edit: iirc though the sliding animation has existed for a while as it's used in the Alexander raids on the conveyor belts.

Oh true, but I guess for me it doesn't have the same feel as it does when you're sliding down a hill or over icy moonbeams.
