Trust me, SC2 is far from Brawl. At least they're aren't actively trying to make it as un-competitive of a game as possible, so that already puts it on top of Brawl.
But, yes, maybe the micro isn't quite as intense, but, there is still plenty of instances where you have to be careful with it. Phoenixes, Colossi (especially with drops, which seem to be not utilized that much at the moment), Ghosts, Sentries, Immortals (to make sure they're actually shooting against something useful), and Templar. I dunno much about Zerg units, so I'm sure there's some stuff in there as well.
There could be a wealth of unit ability combinations that haven't been really explored yet either. So, we'll have to see.
Anyway, the great thing of SC2 is that it can be patched and changed to get micro, if it really needs to.
