Kinda iffy. I never really saw the bonus to the rematches. Point of the Gym Leader was to test trainers to hand out badges. Fighting them again seemed redundant and I kinds expected a penalty for losing to them in rematches like you lose your badge for losing to them since you failed to keep up to the standards of qualification.

We've never had a Rematch system for Gym Leaders, along with two other specific things that a lot of people tend to ask for each new generation. Like with the leaking of B/W I'm going with the there won't be any Rematches until the second set of games (be it thirds or more sequels). This along with Battle Frontier and Move Tutors. I don't expect to see any of these appearing in the primary games for the generation.
