The beloved stat geeks have already researched aging curves in most ways imaginable, and they continue to do so. Yes, aging curves are slight different for pitchers, catchers, and position players. They are also slightly different by body type.
I am sure that with the advances in technology and science, the aging curve might be extended. OTOH, the aging curve was extended due to PEDs use, and now that we are no longer in the steroid era, the aging curve might be shortened.
All that said, the aging curves that I have seen all conclude roughly the same thing.
