I also can imagine that dynamic lights and shadows will be the future. Most shaders have only one purpose: creating dynamic lighting. This concept even uses normals, heights and specularity today. The gpu's do all that real-time.

Currently static light maps are a good way to create moody environments. If I would make a game now then I want to have static shadows as well. This ensures to run smoother today.

But the future will probably be real-time. It will even make much things easier: You don't need light map compilition. You can place a light in a real-time editor and you see results instantly.
