You have to realize that most genwunners aren't hardcore Pokemon fans. Most of them abandoned the series after gen1 or gen2 and didn't come back until much later. They'd sometimes feel the need to give a passing look at what was going on in the Pokemon world, possibly buy the latest game at whatever time this feeling rose in them, and they'd see a bunch of "weird, new, ugly" pokemon that they didn't like, because they really were just feeling nostalgics and wanted to play a game with the REAL pokemon, aka the first 151 one. In essence, the feeling in them was not a sudden renewed passion for Pokemon; it was nostalgia.
Genwunners obviously played gen1. But ton of them also played gen2. Pokemania was "dying" during gen2, but it wasn't dead yet. It was only truly dead during gen3. But Ruby and Sapphire were the first "post-pokemania" games; Pokemania was recent enough that a lot of people still played RS or at least had some knowledge about it, from reading about it or hearing other people speak about it. It had that "Oh, Pokemon is still going" feel.
Gen4 was the actual gen were all traces of Pokemania were gone. No genwunners were keeping up with the series at this point. Yet, Pearl and Diamond still sold well, and being on the DS (the most popular handheld of all time), it was the first gen for tons of new kids who fell in love with Pokemon through gen4.
Gen5 is a different gen pokemon-wise, but it was in the same console gen, and attracted mostly the same people who played gen4; the old fans who had kept up with the series and the young new fans who had no preconceived notions about what "real" pokemon was.
XY and USUM are the games that attracted the most genwunners. There's several reasons for this.
1. Kanto pandering
2. Good marketing
3. Pokemon GO's success
