Machinarium anyone? I'm of the mind that games will follow take an approach like arthouse vs. Hollywood before too long, although it was a non-gamer friend of mine that coined that analogy. More and more, the accessbility of game production, publishing and distribution through online content delivery stores is opening up channels for independent developers to get games out there (Mac/iOS App Store, Steam, XBLA etc.). As a result, you'll get games that aren't like your average 'blockbuster' PS3/360 hit, although major developers play on this too.
My girlfriend's currently working on her dissertation based around the so-called retro gaming 'revival' on platforms such as the iPhone. Of course what's really happening is the same thing as when University students and hobby programmers got their hands on Commodores etc. and started making their own games, purely for fun, or so I'd hope. I'm sure she could offer some of her own views on the subject from her research and writing and maybe I'll convince her to give some here. The nature of technology on platforms such as iPhones means that old trends are repeating themselves with regards to the style of games, hence the current influx of 'remakes' and 'revamps'.
The fact is I'll still play any game of any style as long as I feel some form of 'game' quality come through. I don't want a spoon-fed CGI fest which is completeable within 24 hours, nor do I want a chore of an experience (I won't use the phrase 'learning curve'), I just want a video game!
EDIT: I'll withdraw my comment about XBLA, I just remembered
Jeff Minter didn't really have any nice things to say about them recently and that Machinarium wasn't released on Microsoft's platform for similar reasons about financial crap, publishers etc.
