The current release plan for the Tron characters was in the pipeline for months before they were announced, nothing changed, no mistakes were made, and the team will have had knowledge of the future of the Franchise as soon as they requested their inclusion from the relevant department.
The only thing they were not anticipating was the negative reaction from the community or at least the level of negativity. Obviously it was too late to change the plans at that point, but I do not doubt the negative reaction will have had an influence on similar plans being implemented in the future.
