17 million should be the minimum expectation. Up to the start of October it sold almost 12m LTD and more than 7.5m for the year. The year up to October is usually around half of what a console sells in the whole year, maybe a bit less than half. With these numbers, PS4 only needs 5m more in the last 3 months to reach 17m and 5m would be bad considering its done 7.5m already this year.
If Sony plays all their cards right by getting the 3 bundles to America and making sure there is plentiful supply, 20m isn't completely out of the question (very unlikely though).
