It would be nice if OpenGL on Android benefited Linux ports, but I doubt it will be the case.
Most of the AAA games and the game engines they use are already built to support different rendering libraries. The biggest hurdle I believe is the commercial factor, rewards vs costs and risks.
Having used a few different game engines that don't have Linux support (which is almost all of them) I've always asked why not and the answer is always.. it doesn't make good business sense, market is small and not much money in it.
It may seem like some extra income for free.. but another platform with a wide variety of hardware configurations to test on can end up costing a lot for a large developer.. and they are not going to cut into their profit margins. And the game engine companies mostly just follow the trends of the industry and their buyers wishes. For big corporations the simple fact is.. follow the money.
