I personally love this piece of news.
May could get a return because if they integrate the Champions League that the games seem to be brewing up, Misty and Brock could be back. I'm basing that from the original traveling partners' possible in-game appearances in
that one page of this same CoroCoro issue.
Now if they reappear then it wouldn't be fair if May, and even Max, don't. Although I'm probably seeing this as a long shot at nothing. There is a slim chance for the series to acknowledge the old traveling partners bar Dawn, after all. Although I love Bel's idea. I'm almost certain Gary will reappear, since we're seeing a return for the old Pokémon. And he's in that CoroCoro page, too.
