I thought the article and concept was interesting, though I don't know that I would swap out a utility for most of these. I know they want to emphasize the powers you get from a class, but why use the power system to do this then?
That aside, there are a few of them that are neat, mostly from the active skills. Most of them I feel are slightly underpowered. I would have liked to have seen more at-will utility powers; for example, the moving through crowds power for Streetwise could have a slightly higher level, but at-will. In fact, that's how I would have worked the higher-level skill powers - more stuff you can do at will.
[EDIT] Also, I think this article was supposed to come out next Tuesday. Nice treat, even if it was a mistake!
