I hope Valve isn't acquired by Microsoft. Gabe left Microsoft to found Valve so as long as he's around I can't ever see that happening. Is it known who will helm Valve if Gabe decides to leave? Plagman has been a big name there with the recent SteamOS platform development but I'm not sure who the actual second-in-command would be.
