Actually, I could see both being easily implemented. Again, and obviously, we can use MOO 2 as an example.
It had tactical combat (my favorite) that wasn't in real-time (I was "eh" about it) and if people didn't want to do that there was the AUTO button. Plus menu options prior to starting the game.
Personally, I would like to see a full tactical/strategy game that allows for auto-complete (whatever) and posesses a video playback of battles so we could see a turn-based battle play out in "real-time".
Or, and here's an idea, allow for real-time/turn-based (rounds) battles implementing both micromanaging for those that want it and perhaps player-made maneuvers like playbooks or some such.
