Ludia has been leaking the families for the next update and co-op info to keep the player base engaged. They know the game is stale and people want to quit, so they have been slowly dropping this information in order to keep the players engaged and spending money while they slowly drag out the next update.
1.15 won’t be anything different than anything ever. Just a new feature which will have a ton of bugs and won’t work correctly and Ludia knows this, so they’re trying to milk the last few bucks out of everyone they can.
I mean have they ever shown any inkling that they have a clue of whats going on or how to fix the actual game? They announce things like “boost reset” so that people will buy more boosts and just boost things because the player base knows that they will be getting those boosts back.
If this isn’t the case, just post the patch notes now and show me.
