According to the video:
Two separate units for the Thor: Normal and another named as "Thor (Wreckage)" which awfully reminds me of the crashed Norad II.
The SCV has finally got it's official voice that sounds like a redneck in his 60's along with his appearance (Seen in the Terran Trailer).
The Siege Tank finally has a portrait but instead of a closeup face, his square head (No longer round) is further away and the camera shakes up and down.
The Banshee finally has a portrait with red colors all over like the Siege Tank, she is wearing what Helicopter pilots wear.
The Battlecruiser's portrait is a much more detailed version of the "Admiral" seen in the Protoss trailer but smokes a cigar forever.
The Marine's portrait is a much more detailed version of what can be seen in the StarCraft II website but changes color depending which player owns it, as similar as the Flag in the original StarCraft.
And so far, both returning units "Siege Tank" and "Battlecruiser" have their same voice from the original StarCraft. Thr Thor has a new voice, in which it sounds a bit disappointing to me by losing it's anger!
