Well, Meta, my dear brazilian companion, I feel the needs of making my own comments. Such are as they follow:
1: Yes, it seems they're putting more work on assembling the Zerg (no surprise this far). "Creep Tumor" is gonna become a player's favorite in multiplayer. Expect me to try it as well... next year or so later until SCII is released, of course.

Corrupter's still the same, showing it was a waste of time, since they've shown it on the Zerg launch trailer months ago. Queen is impressive, though. As for the Spine and Spore crawlers, let's hope someone won't make a Starship Troopers mod using it.
2: Loved the Protoss, specially the Nullifier (I'm expecting someone will release a 300 map using it as a Spartan support unit.

). Anti-Gravity is something I didn't see, but I bet the Protoss will be the favorite in matches. It was also a good idea to bring the Recall back, it was my favorite. Ahh, the old times when you held long enough to build a troupe of Reavers and some Arbiters, then Recalling them on the middle of the enemy base... so much chaos...
3: Terrans seemed a little disappointing, though. They're more relationed to some units in C&C 3, most likely examples are the Jackal and the Thor. Jackal reminds me of the Nod Attack Bike, players will rush to get the Factory and some Jackals to harass the workers early. Thor and it's wreckage is a Starcrafted version of the Juggernaught, Behemoth, Avatar, Purifier, Annihilator and Devastator Tripods, with the only exception you don't need an Engineer to get it back online.
4: The only concern I have with game is the campaign. Will StarEdit allow us to make a linear campaign, then allow us, the "innocent modders" to replace the original campaigns, just like we do in SC I? Will there ever be a linear campaign in Single-Player? Will they keep de-emphasing heroes until they're no units, just single-player models? I'll never know...
5: As for the super-unit thing, the Terrans won't have a super-unit like the Mothership or the Queen, cause they don't need it!!! A group of Thors can own them!
That all said, buh bye.
