Well they definitely took some pieces of M:tg, i'm not convinced that was a bad thing. The rules didn't clearly define (well they did but it took some looking) when you took ongoing damage (being on fire) and such things. They cleaned it up and clarified how to take the steps so that in a turn based game the timing actually works.
I have been keeping up pretty well with 4e, I have keep on the shadowfell right here. I'm running it for the first time on thursday. I feel I have a pretty good grasp of all the rules that are out.
Enworld had a link to some images of a bunch of higher level wizard spells....here's a couple of the BC ones.
