Oh, you mean like, their canon anime Pokémon! I thought this thread was about Team Rocket as an organization being in S/V, lol. Which.. I mean that would certainly be interesting! But I'm not confident in the likelihood.
If the trend continues, Meowth could very well see another regional form, and it has been confirmed to be in SV. But I haven't seen any evidence of any other 'Rocket-distinct' Pokémon will make it into the dex. Though hey, I'm not up to date on TR's list of Pokémon over the years so I could easily be wrong, lol.
