gcvijay,
Welcome to the forum. No question is stupid and yours certainly is not.
I'll give my thoughts, but they are subject to change as more data becomes available on FY2014 use. Other people may have an entirely different (or opposite viewpoint).
In the worst case scenario:
a) No spare FB visas available in FY2015.
b) EB1 uses their allocation plus any Fall Up from EB4.
c) EB5 uses their allocation.
d) EB2-ROW uses their allocation. If Q4 FY2014 PERM certifications continue at the same rate in Q1-Q2 FY2015, that is a likely scenario.
e) CO uses the entire 2.8k initial EB2-I allocation in October 2014 to approve some of the cases that could not be approved in FY2014.
Under the above conditions, there would be no available SO for EB2-I and all visa numbers would have been used in October 2014 / by cases still current from November 2014 onwards.
Movement beyond 01MAY09 would not be possible.
If PERM certifications do slow as has been suggested, then based on a halving of certification numbers in Q1-Q2 FY2015, around 6k FA might be available from EB2-ROW.
That would probably be sufficient to move the COD beyond 01MAY09 at the end of FY2015.
It's also possible that the EB1 approvals will settle down to a more "normal" level.
As I said, it really is too early to make a sensible prediction at this time.
I have updated my predictions on the
