I'm a bit lost here, I really want to play Pokémon Rejuvenation, but now that I've seen the spoilers for v13.5, I think that I'll wait for it instead, but I really can't wait to play, I really really want to play, so my question here is, what is the estimated date for this version's release? Because if it's on September, October and so on, I think I'll play with v13 first, because I really really want to play.
