There's the first person shooting, there's the rts elements, it all screams PC. Granted it does look like it was made for consoles, so maybe a small studio like theirs doesn't have the resources to make a proper PC version? Maybe there IS a PC version coming and I haven't heard? Maybe this game will sell well and allow them to make one?
 
Who thinks a PC version is a good idea, gameplay-wise.

I'm not struggling with the controls at all.

Can't help but think piracy would probably make it pointless, look at world of goo.
 
At least this way, those that want to play it, have to buy it.

it needs a SEQUEL! come on 8 dudes at signal crank one out!

Well, since it was made specifically for the XBLA and is a part of the "Block Party" I'm thinking it'll at least remain exclusive for a good while. Both Braid and Castle Crashers eventually jumped to other platforms but it took a couple years.
