Based on Last week DD even if CO applies 8000 from SO, the dates will move into 2008JAN in JULY2013 VB. He cann't apply less than 9000 from SO for July2013VB. And in AUG2013VB he will definitely apply all the remaining SO and this will ensure PD will move to atleast APR2008. And I believe QESEH theory where in CO cann't retrogress in SEPT2013VB since annual monthly quota of 232 visas will be available. May be in the worst scenario he might retrogress in OCT2013VB. Otherwise as Qeseh said in his earlier post it will be in DEC2013 we can see dates getting retrogressed.
