I think this is actually great news for linux users. Although it is not the absolute best solution (that being a native port), it should resolve a lot of issues that wine users experience (such as upgrading wine allows application B to run but in the process breaks application A). It is a bandaid solution but to get the ball rolling on linux commercial gaming this might be what the doctor ordered. When Transgaming went into partnership with EA for their Mac titles it lead to not only more gaming options for OS X users but also brought the attention of other publishers to the OS X space. This has resulted in more native ports for OS X.
