Maybe they should have dropped the 2xAA to get the game running at 1280x720 as is standard for the vast majority of solid games.
Without a frame rate analysis, it's tough to say whether the lowered resolution was a good idea or not, but considering that fast paced games like MW2 (which deliver fast frame rates at the cost of dropping H res to 600 lines) it does seem a bit odd that the SC developers couldn't have done likewise unless the game uses some fairly complex effects that would drop frame rates to unplayable levels.
SC is a slower paced game, so this seems unlikely.
Are the models and environments that much more complex? Who knows.
