While I wish this was true, tower defence may very well NEVER come to Bedrock. Let’s look at some of the facts.
it‘s not that popular
a lot of the aspects used aren’t possible/easily achievable on Bedrock
its quite a complicated game and quite a few changes would have to be made
it takes a LONG time to update this game. Like there was a time where it took 3 years for a major update to be released to tower defence. It’s by far the hardest game mode to port.
So for it to come to Bedrock, it would have to be simplified quite a bit and I doubt it would get the player counts for it to be worth the effort
