For people wondering about the movement and action systems, there's a nice dev video they just put up.

It is a mix (or hybrid as they call it) of Firaxis's Two-Action system, with a couple things found in the older X-COM titles (inching forward tile by tile, stopping movement when spotting enemies, etc.).
It's very alpha-stage from the looks of it, and they said the actual game is 18 months away so I'm sure more uniqueness and polish is on its way,
