I thought it was Destiny at first but then I saw the War Sphinx and his armored glove and thought "Oh shit is this Halo!?" and I squealed like a little girl when I saw Cortana's chip and Chief's helmet.
I don't think the poncho is gonna actually be in the game, I think it was to follow in Bungies Destiny footsteps and add mystery to the 'figure' during the con reveal. But I'm with the artist of the poster - & I think this is kinda funny. ~have you seen the trailer??!
