Just found a post on neogaf that has left me incredibly worried.
It is a dual stick shooter. The controls work really well - it detects if your thumbs are 'drifting' and keeps the control scheme centered to accomodate drift. Hard to explain, but it just works. You do things like double tap to theow grenades, board vehicles etc. Also supports M/k and yes there will be joypad support shortly after launch.
Also kind of weird that people are surprised we are supporting our own platforms first.

the bit that concerns me is the last bit where he says about supporting their own platforms FIRST.
hell no, come on Microsoft, never release this on ios or Android, seriously this is getting ridiculous.
I just hope I'm reading into this too much.
