Since we're all guessing as to what the announcement tomorrow will be...
I suspect that it will be for those that applied after Jan 1, 2014. And, I suspect that it will only be offered to those that are not out of status.
Since they are not offering this to every applicant, based on the language, this would seem to be a fair option...in their eyes. Maybe?
CIC is probably assuming that those that applied after August 28th (or whatever date is on their latest update page) thru Dec 31,2013, are going to be processed to AIP quicker than CIC could get OWPs out to those people, under this new program. Because a January applicant is now expected to receive AIP ~ May, 2015 (based on the current processing times, that might actually decrease in January), CIC would focus on those applicants, while the remaining August, 2013 thru December, 2013 applicants continue to be processed.
Just another theory.
