Over at f4wonline, it was noted that just because Brock Lesnar isn't advertised for Raw, "it doesn't mean he won't be there." At the very least, I'd expect Paul Heyman to come out and do a victory speech. But there is the chance that Brock himself will be in attendance. There hasn't been any reports of him flying out of California yet. It is even a possibility that WWE managed to keep him around for a match at Survivor Series. However, my expectation would be that he and Heyman just come out to cut a promo about the victory over Undertaker. Lesnar then wouldn't be seen until WrestleMania season, where he's rumoured to win the Royal Rumble and go on to headline Mania.
