Copernicus, the code-name of the forthcoming MMORPG from Curt Schilling's 38 Studios. Other than the fact that the storyline is being written by noted fantasy author R. A. Salvatore, we haven't heard any concrete information on the game since GDC2010.
Now, Schilling has unleashed a cryptic tweet challenging fans to find the Copernicus concept art among the images attached to a new interview with 38 Studios Senior Environment Artist Joe Mirabello. Schilling (under the Twitter handle of gehrig38) drops no hints as to which of the images might be the Copernicus art, but it's probably a safe assumption that it is one of the landscape pieces, given Mirabello's job title.
Check out the interview as well as Schilling's tweet.
