Already happening. The Guild[1] (a sitcom about the screwed up real lives of a MMORPG fantasy guild) is the most successful example that I'm aware of --- four seasons to date --- but there are others that may be worth following. (Pioneer One[2], about government agents investigating the weird, is just getting started, but looks good so far.)
It helps to have talent with pro chops, of course; The Guild was created by Felicia Day, who's also one of the acting leads; Wil Wheaton is a repeating guest star.
