OP’s timeline for the wife is a bit of a mess, but it is safe to deduce she became an LPR in 2010. If she filed I-130 in 2010, then her son’s PD is current. From the June visa bulletin, F2B, Philippines:
22OCT11 - final action
01OCT13 - date of filing
The presumed filing date, 2010 is before either date. So a visa number is available.
This has not been the case of Filipinos for a while, assuming it ever was. From the June visa bulletin, F1, Philippines:
01MAR12 - Final Action
22APR15 - date of filing
As you can see F1s from the Philippines wait less than F2Bs from the Philippines.
