The current policy is 100 studs a year go to Vance, offset by 100 Air Force studs coming to Whiting. VT-3 is just about complete with the transition to the T-6B. We just had our first completers over the last 3 weeks.
VT-6 is starting to send IPs to the FITU. This time next year, or sooner, VT-2 should start. 2012 should also see the beginning of Corpus squadrons transitioning.
In terms of training, the syllabus is the same (~90%, there are a couple of difference) since it is the Joint Primary Pilot Training. All the IPs are held to the same standards, while you may see different techniques, they typically are pilot based and not service based.
The big difference tends to how the Air Force runs the studs day. Starts with Stand up etc, but typically, while Whiting doesn't have official stand ups, there are groups of studs studying everywhere.
