It's obvious that Kinect is a big financial success for Microsoft.
Gaming wise I would say yes. Even though I don't own a Kinect, and I dislike motion control in general, all the people that try it have a lot of fun with it (myself included), and I think this is the only thing that matters.
Okay, it's also pretty clear that there aren't any good singleplayer experience, and Kinect Sports, Dance Central and so on are just party games, but, as I said before, the only thing that matters is how much fun you have when you play it.
Edit: I voted "In a way", because it was a huge success for casuals, not for hardcores.
