During BlizzCon 2009, Blizzard revealed plans to put a shopping interface inside StarCraft 2, which would allow players to purchase user-created maps, with revenue shared between Blizzard and the creator. The game came out in July 2010, sans marketplace, and that feature is still missing.

During an interview with MTV Multiplayer, Blizzard's Frank Pearce asserted that the feature is still on the way. "But it's not necessarily something we have a specific timeline for," he said, "which is unfortunate because one of the things that we've found is, especially from our learnings from World of WarCraft, is that these audiences that play these games are very, very passionate and want to experience lots and lots of content. With the StarCraft 2 client and the StarCraft 2 map editor and the Battle.net platform, it creates an opportunity for the community to serve itself with content, if the mechanisms are there."

To be fair, if it did have a timeline, it would be a Blizzard timeline, and therefore could only be specific to the year. Approximately.
