I think PC gaming has some advantage because it casts a huge net over a lot of factors: games big and small, lots of genres, lots of input types, ancient weak hardware to the latest extreme can all be viable, can be tinkered with, developers of all types can produce on it, shared with non-gaming usages. The only way I could see console claiming more of that is if it standardized something similar to a CD/DVD/BD player device, under a consortium and not 'owned' by a single company (or at least easier to license).
