Found the quote... (Destiny)

It's in Bungie's contract that they must deliver a full-blown sequel every two years. This has been part of the plan for Destiny from the very beginning.

“Let’s say Destiny 2 [and] Destiny 3 are out, and we have new players joining the fun. [They] want to play those new games alongside those who have been playing Destiny from the beginning,”

“[We want to ensure] they won’t feel like they’re four years behind. And then, if they want to, they’ll be able to go back and pick up the old content on their same character. So we’ve done a lot of planning for how that’s going to work, to not make people feel like they have years worth of levelling up to do.”

Does work to confirm the "full-blown sequel every two years", but how would that tie in to a ten year plan? Will we have a Destiny 5, where out level 90 characters interact with level 2 characters? Also, they do heavily imply that you will be able to take your gear back with you to the first game, so we'd be seeing some pretty massive compatibility updates... And what of last-gen? I doubt they'll be getting a Destiny 2...
