Hmm, I'm thinking the iPad launch as something to do with this 4.0 announcement. This is the first time in a long time that Apple hasn't followed the iPhone trend. It all started with the 3.2 delay. We have still gotten OS 3.2. OS 2.2 was released in November; 3.0 announcement was in March. The trend has finally been broken. Maybe it'll be April 1st. This would be great promotion for the iPad.
