Well, i've also been curious about 4E even if i didn't really like 3E (too much work to get a PC done, too much "options" for everything like 2E and too much wargaming), and after reading a bunch of reviews i'm still unsure what to think about it.
I think it does get a lot of things simplified (which is good, i always thought that the spell list from basic where all that was needed to make a wizard or cleric work, and there was no need for tomes more) and running more smoothly (mainly by restraining the options available, fusing things together (calling them powers) and generally adressing a lot of concerns from previous incarnations (low starting hp, classes and races balance)), even though there are still parts which do not agree with me personnally (the whole wargame combat and the powergaming feel of it all).
I'm not planning on buying a new set of rules yet, but i'll certainly want to try it a few times before i make my mind (hopefully 2 of my friends have already bought the thing and are more than probably creating new PCs as we speak, so i'll have my opportunity soon enough)
