Another one bites the dust! In the future everything will be produced by 1 company?!
I expect 10 years from now only the three console manufacturers to remain, together with maybe a dozen or so of the biggest publishers. They'll probably each own a ton of studios developing for them. If graphics fidelty continues to rise, expect the cost to develop a triple A title to rise even further.
On the other hand, there seems quite a growing indie scene developing lots of interesting/niche games. At the same time I think we'll see a growing number of "cheap" or even free game engines, like unity, that'll allow those indie developers to start creating a game immediately instead of wasting time writing their own tools.
