Well, I just watched I video on YouTube by Curse, and Lindsay was showing off the "swag bag" She shows what the "swag bag" contains. At about 1:08 in the video, she then pulls out a Minecraft XBLA Minecon 2012 cape code. Which has a picture of an Xbox Live avatar wearing the cape on it.
It is blue, which supports what Mollstam said about the 2012 cape being "pretty and blue," and it has some sort of gold symbol on it, I couldn't really get a good view on what it was...
For 2011 the Minecon cape you for the XBLA version was the same as the PC version. I'll let you guys decide.
I think it could be the one. My friend told me there was a poll a while back to vote for the design, this was one of the designs and looks identical to that one. I think you're right! http://media-mcw.cur...ineconCape1.png
That looks pretty sweet, I must say, but when could we vote?
