The picture above was snapped by master patch eviscerator Matt " Cyborgmatt " Bailey at Valve HQ. As PCGamesN report, Valve flew him out to Seattle for The International, but failed to confiscate his camera and erase his memories. The images on his Twitpic account show a few Dota 2 trading cards and a sign inviting readers to "spend $40 to get a pack of cards guaranteed to contain 1 courier." A trading card game that can unlock in-game Dota 2 rewards? This could be the end of Owen.
A prototype Axe figure was also spotted with a plaque suggesting that we'll be able to buy it "summer 2013." Dota heroes would work perfectly as a collectible series of figures/cards, but which one would you want to own? I'd be interested in a six foot tall remote controlled Roshan myself. Pictures follow.
