I dont think this type of internal crisis will have much effect on Tron, because the person leaving might be part of the people that has the idea, but he is not the real technocrat that worked on the project, as far as other team members are still there and the technical developer, the project will continue to move forward.
The project has already been established and there is no way the community will have a change of mind about the project because of one man, when it is not the man they are investing in, but the project itself and the product for the profit they will get from it.
