Since the 1.19 Wild Update has been released there should be a survival reset. Especially since many people have already maxed out and it kinda dead atm.
They probably where waiting for the latest version to release, Now it's out there could possibly be some back end issues or bugs and such that they may need to fix. My guess is that they're probably going to be working on the reset now or very soon. I doubt we'll be waiting particularly long though. Yay for frogs!
