Between that and the humble indie bundles (or just indie games in general), I think it's fair to say Linux gaming is looking much more exciting and healthier than it has ever been in the past (at least the recent past).

Does that mean it's "about to take off?" I guess we'll just have to wait and see. I certainly hope so. Games have always meant pushing technological boundaries, so if games get big on Linux it will hopefully move the whole OS forwards. Finally, the year of the Linux desktop is upon us! (...don't worry about those pesky locked-down mobile devices)

Well... a man can dream, at least.

Yes, of course. What is your point?
