I sort of hope there will be a new console company that provides good competition to the other two. That would help stop MS and Sony being too lazy to release new consoles and keep the gap between PC and consoles at a minimum. But that's not going to happen and I expect they'll just do whatever makes them the most money, regardless of the quality of the product.
I agree, id like to see an android or apple, or sega console again for example.
The thing is though, (at least i think so) releasing next gen consoles early might not work money time
when a new console comes out who buys it : rich SoBs, and enthusiasts,
i would say it takes about 3 years for causuals and people less fortunate to get one, thats about a half way mark. I imagine that most of there markets (all consoles currently) came about the middle period.
That being said, they have to drain that market for 3-4 more years. Releasing a console every 3 years unfortuanetly would not do well. Money wise
