E-Sports in 10 years will be great. But that all depends on what games remain relevant during that period. CSGO might still be a dominant esport in the long run due to the fact that it still has a good fanbase backing it since 2014 and the game has boomed during the pandemic (especially among Chinese investors)
If Valorant plays their cards right and makes sure that the game isn't just a competition between EU and NA and get Korea involved more, then Valorant can easily be a dominant force in Esports, and could potentially be the face of FPS shooters in the next 10 years.
MOBAs need a remodel since DoTA 2 and LoL hae been the bipolar forces of the genre since forever. No new MOBAs want to enter the ring and contest them since they're afraid they won't make it, and both games are good and drag in a lot of viewers but it seriously needs something new to pump some new blood
COD, sadly, I don't see staying as a contender in Esports much longer, the majority of the fanbase only plays the game, and they don't care about any team in the league other than the Atlanta FaZe, and the game is turning into a game you want to play casually with friends, not a game you take seriously
Fortnite and other BR games, do I have to say this? They're dying or dead, probably not even making it past the 5-year mark other than Apex and PUBG due to the intense popualrity of the games and because the fans are dedicated
For the games that last the test of time, they will boom and prosper as investors realize that esports means money in the bank, and it will only get bigger
For the games that tried but failed to remain popular, but failed to make it, GG.
