Starcraft II will be 3 games

Yes, instead of warring about my job and this economy, I can't wait for Starcraft II to come out. And some googling later I got this link:

Starcraft II will ship in 3 parts, 1 terran campaign and 2 expansion (zerg and toss).

Have to say I am a little bit disappointed, to save cash I will just buy the first one and wait till the other 2 drop in price.
