After a rather slow start, this article turned interesting. I found the blurbs on the tiers to be less than inspiring. (Yay, molest furry woodland creatures in the heroic tier. I always feel sorry for wolves).
But the crunch at the end made it worth it. Glad there aren't an absurd number of encounter powers- game balance would have been an issue if you quickly reached a point where per encounter powers = expected rounds of combat. You'd never need at will powers.
I want to see more on the recharge/regain mechanics hinted at however. Those strike me as a major power boost in the upper levels..
I am a little surprised that the class model is based on the sorcerer (limited powers known, swap out as you level), since he's still a johnny-come-lately across the history of the game. I think it works, however, since everyone is more or less on this model.
I don't think I like the hint that paragon paths are required, though.
Items for new, high level characters seem to work, though I wonder how that compares to what you're expected to gain as you level.
