The footage could potentially be from the singleplayer campaign of the StarCraft 2 trilogy's first instalment 'Wings of Liberty,' as Blizzard has revealed that a Protoss "mini-campaign" features in the PC real-time strategy's central Terran campaign.

While the most recent launch window given for StarCraft 2: Wings of Liberty is the first half of this year, that was before the beta test failed to start in 2009 as had been planned--and Blizzard has said it expects testing will last for four to six months.
