There's already 700 people working on epic mickey 2. Future call of duties and battlefields will just use 2000 employees for next xbox and game prices will be 80 dollars and xbox live is gonna be 70 dollars. All game endings will be DLC.
That's kind of what I expect. I can only imagine in the future games will have both a single player and multi/online pass. 10 bucks a piece if you don't buy new.
DLC will be necessary to get the complete package. And I imagine lots of games will incorporate the Skylander models with toys/figures/cards to supplement the experience.
We are going to see a LOT of ways to pay more than the asking price to get the entire experience.
