That's a tough one,
becuase like you said it does make sense. I would try to feel him out to see if there was anything that he wasn't comfortable with so that you can get that/those objections out of the way and he will go to his partner in the best frame of mind for making a favorable decision.
One thing I would make sure I do is get get at least a small close, something like "Great, When do you can I expect to hear back from you?" after he tells you when, ask "Should I call you or come down to meet with you?". Then make sure you follow up.
