Did we, though? Or maybe FTC could prevent further consolidation that will eventually result (and is already) in anticompetitive practices?
I can only see this as better for competition than Sony running away with the high-end console market, because then there's realistically only one console to buy.
So now your choices will be: 1) pick the console that has more of your favorite games, or 2) now you have to buy BOTH consoles.
