Artwork Trailer, 1:35

Interesting conclusions based on a screenshot from the SC2 artwork trailer

Obviously it has Zerg features. Looks like a small Lurker...
Look closely... is that... a humanoid had?
And we know Duran raised the Hybrids in Statis Cells...

WTF?
Looks like a Goblin in Protoss Armor. Hybrid?

Looks like Zerg eggs maintained by Protoss tech (notice the Golden texture)
