I am 20th Nov Applicant and I had regularly followed the CIC caps on thier webiste and I know that till 15th Dec 2015 the total applications for 2281 was showing as MAX 750.
So first thing I am sure of is 2281 CAP is not reached since 1000 is the limit.
Secondly, FSWP program is FIRST COME FIRST SERVE and looking at the same website the count of all the NOCs was not more that 17000 so it has actually not crossed the 25000 limit. See that I am talking about anything related to spreadsheet since it may have not all the users registered.
So ALL those whose file is reached by 31st Dec closing day of CIC office then it will be included for NOC 2281 and for all the other NOCs except whose 1000 cap has been reached before that.
2281s has high hope and keep your fingers crossed and sit tightly you never know when you will hear from them... Keep checking your inboxes
The only thing which I am not sure about is the situation where if 1000th Applicant got rejected then they pull other candidate or not for the same NOC to set the mark of 1000 or simply they stop there.
