I think Ryan and THE1 hit the nail on it's head as you cool folk would say.
As with any industry, they try hard to make money. What makes them money? People. People buy games that are well known and are spread by word of mouth. What is this called? "Mainstreaming" an industry...
The Wii and XB360/PS3 really were great proof of this already happening. The Wii capitalized on the Mainstream market (or, "Casuals") with it's easy to play titles and over all "lifestyle" type games. (Not all of them were like this, of course.)
The XB360/PS3 capitalized on the Mainstream market by providing major multimedia experiences such as NetFlix and Hulu. (Plus a bunch of other downloadable services that make you more (or less) connected to other people.)
This is already happening.
