Well, to be fair, Starcraft 2 isn't much in terms of graphics.
It's pretty, but I don't like the cartoonish feel of the graphics. It always felt strange, come to think about it - the cinematics were amazing and they had this gritty sort of feeling, but the game itself didn't match up to that.
But then again, this is Blizzard and this is Starcraft 2. It's the sequel to one of the greatest (hell, THE greatest) single RTS game of all time. Anything regardless, people will play it, not because of graphics, plot, story, feel, etc, but because it is Starcraft.
I know I will. I've missed a good game like Starcraft and I'll eagerly await this one. Legacy's massed Goliaths will walk onwards once again...
