Gamevideos has made a video of a StarCraft 2 Terran multiplayer gameplay presentation from Blizzcon. It probably looks than any CAM movie you have downloaded, but it is very interesting and revealing nonetheless.
The video shows new buildings, units and new capabilities in a context where they are exceptionally efficient. To the extent that they may even seem very overpowered sometimes. In reality, those units are just likely to be highly-specialized.
Either way, if you like RTS games and are hungry for StarCraft 2, this one is a must see.
