The beta for Pokemon Go is apparently ending very soon, this news came via an email that was sent to the beta testers. The email was then posted on MyNintendoNews. Here is what the email said:
We’ve had an incredible time field testing Pokémon GO with all of you. Your battles were epic, your wild Pokémon encounters were fun, and your feedback helped lay the groundwork for a very unique game.
On June 30th, we’ll shut down the Pokémon GO field test. Your app will not be playable any more and we’ll delete all gameplay data to prepare for the official launch. Stay tuned to our social channels for more information.
Thank you for sharing your feedback, experiences, feature requests and many valuable insights. We have learned a lot from you and couldn’t have done this without you.
The Pokémon GO Development Team”
Since E3, it’s been believed that part or all of Pokemon Go would be released in July, as this was stated in part by Shigeru Miyamoto. Whether the ending of the beta will confirm that is still very much in the air.
