I've heard and know for a fact R&D is going to be released before combat.
Mainly because once the R&D code is finished, it's done and the coders can move on,
but combat will continuously be revised and updated and plagued with millions of suggestions. So I've heard, anyway.
Hal, you're obviously misinformed, big Phil has facts on his side. Seriously, get a life and stop trying to start silly rumours to make yourself feel important Hal. Take a look at his little 'teams' bar underneath his avatar, what he's said is obviously the official response.
