>>55495647To be nice, I also made a list with the ORAS Mega Evolutions if they decide to just do all of them in one go while the concept is returning.

>presumably every oneThat gives us an even bigger estimate of at least 198 Pokémon, with Hoenn taking up the biggest increase here for one obvious reason. Out of what's not here, I'm almost certain that Unova will have a handful more added due to its complete absence in Legends Arceus minus the obvious new regionals and Enamorus.
If you're in the camp that the Hoenn starters and main trio won't happen, then Hoenn would go down to 31/135. The slightly reduced estimate in this scenario is 186.
>>55495724It's certainly harder to predict post-Kalos additions that make it in. It is interesting to note that the only line here thus far that got a later evolution was Scyther.
