I doubt this. There will be PS4s getting through, Sony will not want shortages to stop their momentum and there is nothing to suggest that they have struggled to produce the amounts they will need. What may be muddying the waters as someone looking to simply go and buy one in a store is that many people who pre-ordered later will be getting their PS4s between now and christmas and so I suspect that many of the PS4s being shipped are going to these buyers rather than going on the shelves.
Wait a week or two, I suspect the situation will improve especially as they try to get stock on shelves in time for black friday
EDIT: Also don't take shipping dates from stores too seriously, they are usually placeholders and are put back as far as reasonably possible to avoid disappointment for buyers - usually they will ship before these dates
