I dumped money into cedega for almost 2 years and never saw one bit of progress, and no responses from any developers. Then, Codeweaver's releases Crossover with TF2 support, so i gladly gave my money to them and have been nothing but pleased. The results speak for themselves, the developers are accessable, and the company directly gives back to Wine.
For curiosity, I downloaded the "demo" of cedega a month ago to see how far it has gotten, and it couldn't run anything for me, not one game. On the same system, crossover games is running TF2 great.
And, the news recently that Codeweavers are working on a new GUI for crossover, which should make Cedega all but redundant.
