It is perhaps worthwhile noting that the CIC guy in the video is not the only source stating that they will clear the backlog between September and October. If you take a look at the official processing times on the CIC website it states that applicants: "Between February 27, 2008 and June 25, 2010" will take 76 months to process. Funnily enough, 76 months from June 2010 is October 2016.
Without considering the changes to the system, you can expect CRS score requirement to be around 550 if they are inviting around 2000 applicants per draw. Of course there are many more unknown elements; the potential changes to CRS are just one. If OINP starts up again as is widely expected, for example, at least for a few draws into next year the requirement will likely go up considerably, likely above 600. It won't obviously be a long term thing as there are limits to the number of people that can be nominated through OINP, but for those whose current visa is expiring it could be quite a big deal!
