After SummerSlam 88, I don’t recall Hogan and Andre ever crossing paths again in the WWF.  And after Savage retires then comes back, he really never interacts with Hogan again save for that one tag match against Jake and Beserker.  It was almost like they were keeping them in their own universe.  why?  You’d think there would have been some money in Hogan and Andre reuniting.  
Never thought about it, but yeah, you're right.  Hogan and Savage I understand keeping them apart because of A Show / B Show dynamics and their relationship was on-again off-again at the best of times, but yeah, they could have popped a number with a Hogan/Andre v. Earthquake/Bravo tag match somewhere.
