In the "Behind The Scenes of Skyrim" you could see one guy working on it, so i think it's quite possible that they show it at GDC 2011. But then again i don't really know how long it takes to make a good trailer. Since you don't wanna show too much but still want give a good sample of the game.
Even if this post made any sense, it still wouldn't be valid. Pete Hines said it would be in a month with AN "r" in it, NOT A or ONE "r". So even if there was a month that had 5 "r's" in it, it would still be possible to see something in that month.
