Why would they jailbreak it at all? 3.2.2 is NO different from 3.2.1 except for plugging the pdf hole, which can be done through cydia. Seems like a waste of an exploit for me to even attempt to jailbreak it.
The reason why they would JB 3.2.2 is because Apple is shipping new iPad's with 3.2.2 installed. I just got mine today and was unable to Jailbreak it because of that.
I dont have the link, but the dev team just released news that no jailbreak will come out for iphones 4.0.2/ipads 3.2.2. They plan to wait until 4.1 is released to bring out their next JB tool
