All media is going through a transitional stage. Lower budget, still high quality, independent works are becoming much more popular because the technology to make these things are within reach to anyone with an ambition to create. Music went through it with mp3s and the rise of digitally/electronically created music. Movies are going through it with the rise of affordable video equipment and editing software. Games are going through it with widely available toolkits, game engines, middleware, stores, and a gaming device in everyones hand.
I wouldn't say the transition is to better fortify gaming as an artform, it's more that developers are able to do things we weren't able to do 5 years ago at a fraction of the cost with a fraction of the staff. They're able to do this with no overhead. Allowing them to do what they want and not do what will guaranteed sell.
