I don't think game graphics are going to get much better because I don't think CPUs or GPUs are going to get much better or faster. We seem to have hit a brick wall in that area.
Ignore the things you can't change and focus on what you can change. Good advice.
They should also stop using 100-gigabyte Blu-Ray discs to distribute games and start distributing games on Fluo-Ray discs that can hold ten terabytes. That would allow for larger worlds and more replay value.
