Will Valorant destroy the overwatch playbase?

Games go through phases. Most of the newer games get hyped up cuz players want a new experience. Eventually, it'll start to die off. When fortnite was a big thing, so many game studios pumped out clones that stole some of fortnite's player base. However, everyone soon went back to fortnite when the hype died. The same will go for valorant imo.
