I wonder how people will remember Gen 7 in general in about 15-20 years from now? No.38677547 ViewReport
Remember that pokemon gets new gens ever 3-4 years, so there will be a new generation of kids (no pun intented) that will start with any gen.
Will people even remember Sun and Moon are a thing? honestly i just don't see myself in 2039 looking back at Sun and Moon ever, it just seems like a filler gen.
I think it will be the FF2 of Pokemon, no one but hardcore fans will remember it and it will still be as hated as is now.
