Gary probably left because the writers didn't feel that they could string out the rivalry for any longer. Or perhaps they just got tired of him.
OK, kidding, and fair point. But I still don't like to think of Ash and Gary getting a three-season-long saga to end their story, and May and Drew only getting one season that's largely regarded as filler anyway. It's uneven. And like I said, there are some differences between Ash-Gary and May-Drew as current canon stands, and all of them point to Drew sticking around a bit longer. Which isn't to say they prove the writers' intentions, but IMO taking them into account can't hurt if we're trying to figure out what's going to happen.
Well, Ash and Gary's rivalry wasn't resolved in Kanto, was it?By the looks of things, the BF saga may be the length of the original Kanto, 80 something episodes.
