This is the worst case scenario I could think of...
Dates wont move in July (or just few weeks with regular Eb2I quota, not from FB or EB SO) becos CO has not figured out the SOFAD yet and he thinks its still too early in the fiscal.
My guess is dates move only in Sep, I would even bet it will be current for all EB2 categories and even some EB3 categories (except India) - causing random approvals and possible wastage.
From COs perspective, date movements always seems only to generate demand (so that he can save his...) and if thats the case what I said seems to be logical...
Here is explanation of the logic:
If CO thinks that there is going to be more usage in EB1 and EB2WW in the next couple of months and if he is not 100% sure about what the SOFAD would be (the way he has been cautious all this year, there is no way he will be 100% sure of the SOFAD even for Sep) - he will NOT move the dates in Jul/Aug and he may end up with around 43k SOFAD (25k EB + 18K FB) and he has to add a buffer of around 20% to it for cases that would be RFE'd, duplicates, abandoned, etc and he may end up with a 50k SOFAD to be allocated in one last month of the Fiscal. So he has no option other than to make every EB2 category current (becos as of now there is only 48k EB2 total demand) and he has to move EB3 dates for most of the chargeability areas where he is not sure of what the demand would be (for some chargeabilities he may have to make it current).
A SOFAD of 50k is highly unlikely as none of the experts predicted that much but it is not impossible either (with FB SO and the downside of CO being cautious all these months, I would even say it is possible).
Also this would be possible, only if CO truly thinks that he should not waste any of the visas. For any reason, if he thinks that CIR would be out in some form or another next year and he can recapture all the unused EB visas from the previous years, then he will not move the dates at all, even in Sep.
I know it is pessimism to the extreme!!!
