This will not happen, they never bring good new games. Everyone is asking for minerware, duels and old games coming back but they bring a new game Mob who that flops again they dont listen to the java community, this is also the reason that they lose all there players.
Trust. They’re coming back from less than 1000 players on Java edition daily the past few years. Slowly it’s growing, adding more budget for the games (slowly updating existing gamemodes as you can tell), then I believe (and assume, but I ofc never know for sure) they will consider adding Bedrock gamemodes (back) to Java edition. This takes time however, adding all removed gamemodes of the past few years back would let them die out instantly, that would never work. They will always need to take it slow.
There’s currently a good variety of gamemodes. I feel like rotating a few gamemodes every few weeks would be a good idea though! However, that would be a completely different suggestion. I might suggest that later on, also taking the options into account. For now, I don’t think this suggestion would be a good fit looking at the current variety and community requests.
We’ll see in the coming months what they are (secretly) cooking. Make sure to keep an eye out for the public update board!
