The final WAIK has been released, get it here. I know a ton of people have been waiting for that... finally Windows PE 2.0 is available for the masses.
I'm still holding out for WSS 3.0 though. I was hoping they would have released it when Office 2007 was RTM'ed, but I guess we'll be waiting for the GA of 2003 SP2. Although from reports about the quality of the 2003 SP2 RC, I guess I could probably use whatever is in that!
