Really? I have faith that if Greg is as involved in the story as he was in the later years, it will become a tangled trainwreck again. I couldn't agree more. Implying he doesn't learn from mistakes... :/ I'd just rather see a new writer get to take the wheel for Bionicle 2015 for a bit of diversity in storytelling. I'd like something a bit different for a change. But in all honesty it's pretty safe to assume that Greg is doing the story for 2015 and on since he's still active in Bionicle discussions on the LEGO Message Boards, which indicates he either has too much time on his hands where he chooses to spend it on the LEGO Message Boards with nothing better to do, or he is still working with LEGO on stories, especially Bionicle, therefore he's staying in touch with the fans about the Bionicle story.
In my opinion, LEGO's whole Greg Q&A they have on the LMBs is a great way for LEGO to make Bionicle 2015 a continuation of the story rather than a reboot because it allows for the fans with questions to have them answered so that they'll know what they need to when the story does start back up.
