The only drawback would be that if they announced that they were developing the game today it would be what, 2007? before it would be released. CivIII has been kicking around for how long? Four years? And Warcraft III has been sent back to the drawing board so many times the little orcs are getting dizzy (The sounds of "Unk? Hook-ah" must continually echo through Blizzard studios as the orc grunts march back and forth from E3 to Gamespot to the re-write desk and back). These guys are all great designers but they are hell on those of us waiting - the last thing we need is for them to team up. My heart can't take it.
