I have not seen anywhere posted a specific date for ending, and the following post from FB would support the thinking that they may be limited time:

"The Reebro tried to make a premature escape into the wild earlier this aft, and might not appear at first for some users. Deleting and reinstalling the game should entice this monster to make an appearance! Don't worry about losing your progress - your accounts are safe and sound on our servers, and when you log in via the same method as before, your account will be waiting for you!"

Formatting is mine - the word premature seems to indicate it is not permanent.
