Online play for StarCraft is stupidly competitive and no doubt you're all looking for ways to prepare for StarCraft II's online throwdowns. With that in mind, Blizzard has released screenshots of the three faction's tech trees.
The tech trees, posted below, look somewhat similar to that of the original game. My memory's a bit hazy but it seems like there's been a bit of rearrangement. There's no doubt a few new units so that's understandable.
As Giant Bomb notes, these trees could change during the game's beta. If you feel like printing these out and putting them on the back of flashcards though, I won't stop you.
