I think that the watch will make devs think how to extend the experience of their games by extending game play through the extension rather then try to just port a game over. Since the watch extensions are not just notifications but can have some interactivity, the things they come up with will be interesting. I would love it if some of that interactivity was brought back onto the phone notifications as well.
I said the word extend 3 times in one sentence! Wow i must be tired.
