I'm a little confused and may be missing something. My understanding of this goal line so far is that we earn one Griffin Egg through the Errol goals so we can hatch 1 of the new griffins for free. But what then?

Are we going to be able to earn these Griffin Eggs through future events like we're able to earn Academy Scrolls or Crowns or will they be random drops from Griffins? I'm not seeing how this is going to play out long term so I'm going to hold off until we have some concrete answers.
