Huh, these throwback special research tasks are interesting. I don't really care too much about the individual ones, but the final that gives Genesect as a reward, that's pretty awesome. Very happy to have a way to get Genesect that doesn't involve paying an unreasonable amount of money or winning the EX Raid lottery. Though, I must admit, I'm a little stressed about getting that Genesect, as you have to complete all of the first four researches in a limited time in order to unlock the Genesect one. I tend to take my sweet time with special research (still haven't completed the Jirachi one), and with the way things are right now, I don't know if I'll be playing enough to complete all the tasks.
Aside from the Genesect, the interesting thing about the final research is that they specifically claimed we'd get Galarian Meowth, Zizagoon, and Darumaka, as well as their evolutions, which seems to imply we'll be getting Purrserker and Obastagoon, our first Gen VIII Pokémon before we even get Gen VI or VII. That's fun.
Oh, also looking forward to Pikachu in the Rayaquaza and Charizard hats. I have plushies of both these, so that will be fun to get in Go.
