Next?
By my count, it's 21 hours 15 minutes (as I post this) until Mewtwo leaves as a raid boss. Still no notification about what's next. Or will we have to wait until 2 PM tomorrow (PST), and see what comes out of the first new Legendary Eggs? Or will we have a day off from Legendary raids, like we did before Groudon came out? Doubt that, Niantic doesn't want to shut down that revenue stream.
Current speculation is that Giratina will be the next new raid boss, and we might get a return visit from Rayquaza or Groudon (before or after), with possible shiny forms. Other that those obvious choices, any guesses? Maybe shiny Mewtwo, with either Shadow Ball or Psystrike as charged moves - no, too early for that. What else?
