I spoke to my enlistment coordinator about 2 weeks ago and she mentioned the issue of not having enough candidates being available. She said if they can't fill all the spots then just not doing that session of FS is a very real option. Not sure if that's any indicator on current demand.
I'm in the same boat waiting for a call. Personally I'd welcome a January session as it gives me more time to prepare. That's just me though.
Hope we all get a call
