I might be wrong, but I have a feeling that this trend of of mid-tier publishers going belly up and rapid consolidation will continue, at least in the console space.
I would have thought the industry would have evolved into more of the movie studio publishing model, where there are only a dozen or so major studios.
It seems more and more like the industry is going down the television/radio model to me, though, where you have NBC, CBS, ABC and Fox as the major players that own everything. I wouldn't be surprised if in 10 years the only major publishers left are Nintendo, Activision and EA. It may seem shocking, but that's what has happened in other major mediums in the past. We just don't realize it to some extent since video games are still so young.
edit: and Valve. How could I forget valve.
