ksur23,
On the basis that CO will approach FY2014 similarly to FY2013 (and I think that is a fair assumption), I would expect fairly severe retrogression in the October 2012 VB because, at that time, only the initial 7% allocation will be available (252 visas / month).
I wouldn't expect EB2-I Cut Off Dates to get back to 2008 until around July 2014, since porting cases with an earlier PD can probably consume the initial allocation. How far the Cut Off Date can go in FY2014 is entirely dependent on the amount of spillover available.
