Pepperdine University hosting Zoom with Mike Richards

You didn't miss anything. Mike barely talked about Wheel compared to Jeopardy!, which shouldn't be surprising, but it was clear that that was the only show the host was interested in. The Q&A portion had no Wheel-centric questions.

The only Wheel-related discussion was Mike saying that Pat is really funny and very fast on jokes and callbacks, and that Vanna is really nice to everyone. That was it. The rest was discussing other aspects of his career, with a lot of discussion about Mike's successful pitch in rebooting Let's Make a Deal. One interesting remark was that Mike considered being EP of TPIR/LMAD, "the second best job in the world", only behind being EP of J!/WOF when Harry was still doing it.

Regarding the obligatory question: "Have you decided a new Jeopardy! host yet?", Mike said that he's "optimistic" they'll have a decision made by the time the next season tapes in August. Mike himself is in the running along with the 14 others, but the final decision will be made by Sony executives.

Mike mentioned that he met Vanilla Ice on "a show I produced very recently". CWOF Season 2, perhaps?

Yeah, I kind of figured he wouldn't speak that much about Wheel given Jeopardy's current hosting search and his pretty extensive career outside of Wheel and J!. Interesting it's not definite they will have selected a permanent host by the start of tapings for next season.
