Well they aired a "next time" promo in episode #1308, and the show was on hiatus for 2 whole months before the new episodes started earlier this month. Plus, the strike is officially over and MADtv will most likely get back to production soon so if anything they would have promoted the next installment. Besides I think the entire purpose of the Rice & Beans Tour was to see if there were any strip clubs in the areas Bobby and Johnny visited; after all that's what Bobby pretty much kept looking for.
