I recently decided that it would be good for me to jump back into Bionicle as a serious hobby, so I'm starting with the basics -- that is, reviewing the Wikipedia article. One thing stood out to me that I'm wondering about.
Throughout its history, the Wikipedia page has made reference to Bionicle being planned to last 20 years. The earliest reference to this plan popped up in an anonymous edit on 09:13, 28 December 2014, which states that, "Even though both themes [Slizers/Throwbots and RoboRiders] were short-lived, they proved to be popular, prompting Lego to create a new theme with an original storyline as a product staple to last at least twenty years." Variations on this statement appear under the "Concept" subheading until Wikipedia user Bigwhofan added the following to the "Generation 1" subheading: "A total of seven different story arcs were originally planned to be carried out over Bionicle's planned-twenty year tenure. Only three were ever completed, while the fourth was altered to end prematurely after the announcement of the theme's cancellation" (23:32, 27 September 2016). This statement was minimally altered until removal on 16:45, 23 March 2020, with the only remaining reference to this 20-year plan being in its current form under the intro.
The most frustrating thing about all of this is that there is no reference. Have LEGO or Greg indicated an original plan for Bionicle to last two decades? If so, has there been any information on what the full seven arcs would have been like?
