I doubt it's an RTS. They're not capable enough in terms of production values to compete with that market segment. Low-budget RTS just doesn't have the right ring to it, does it.
If it IS, it'll be more like an RPS.
I personally think we'll see something like Dhruin mentioned, or a straight-out Din's Curse in space.
The mercenary bit makes it sound like a Privateer game - and I'm definitely interested.
Loved Din's Curse, except it was too random. It needs direction and story. Rogue-likes are too abundant and most are free. Din's Curse doesn't set itself apart enough to really be worth the price - not to me, at least - though I did buy it. I can't figure out how to re-install it though, as I lost my original mail.
But I digress…..
*EDIT*
Just noticed that someone made the same point. Sorry
