I would disagree here. Nobody likes fragmentation. If Valve can't deliver AAA on linux right away, then this will likely go the way of Ouya. The most interesting thing here is the streaming which could act as a bridge until we see native Linux AAA games.
Lastly, DirectX is so widely used in game engines. I haven't seen any hard evidence (not coming from Valve) that OpenGL can meet or exceed DirectX capabilities. I'd love to see real data on this.
