My two cents.....
As has been made amply clear by Canadian PM, that the goal is to induct immigrants who fit in the system easily. PNP, CIC, people with job offers are definitely in a better position compared to the guy who will land and start searching for a job.
As Phil pointed out, each state is giving out 5000 PNP nominations each year. There are 10 states ie : 50000 PNP nominations. It can be expected that atleast 12000 applicants will have job offers \ canadian experience because they completed their studies in canda.
The target for this years immigration is 65000.
So your chances are 65000 - 50000 - 12000 = 3000
Sad but true
