Umm no, I don't think so. They will definitely put up figures of the first week, or at least first 10 days of applications received. That MIGHT / MIGHT NOT be 300. Well, it's all just speculations. Lets see what they do. No one can actually say anything right now, because of few factors that are involved this time.
1- ECA [few got lucky, and than many others got stuck].
2- IELTS [minimum 6 in each]
3- All NOC codes changed this time, so no NOC repeated from last years. So, many applicants weren't prepared including 2147 / 2174, and those who were prepared got heart broken. I guess at least 50% on this forum that are applying for 1112 were prepared for 1122 so they got a tiny edge here.
4- Even though it was launched on May 4th, but First application that entered CIO was on Monday [and that too with old forms]. Most of the applications started their journey from Monday the 6th. With in Canada / From USA applicants got real edge here. Than South Americans, than Europeans, than African + Middle East and lastly Asia.
In the last, the only thing I could say is, FOR GOD SAKE CIO, GET YOUR ACT TOGETHER AND POST SOMETHING, SO THAT WE COULD CONCENTRATE ON OUR FREAKING JOBS ;D haha
