Answering my own question:
I checked out the 5 seater raven in person today, and the answer is no, there are still no vents for the 3rd row.
This is a bit of a deal breaker for my dog with long trips.
So is there now a C pillar vent for the raven 5 seaters? This should be an easy thing to determine. I would rather not have to pay for an unneeded 3rd row just to get adequate AC coverage.
