Ritchie's return to the anime

In addition to Ash Ketchum returning sometime after gen 10, I would say it be fair to bring back Ritchie back to the anime as well. For a very long time, I suspect that Ritchie would be no more than about 3 or 4 years older than Ash Ketchum which would also explain his experience. On top of that, some of the newer pokemon that will assist him as Ash will enter one of my proposed regions. I would also have Ritchie to be taller and have him as a major Character.
