That said, the position is not much different from saying the following: Any truthful answer you receive is very dependent on all of the context surrounding the situation resulting in the answer remaining true/static.
Thing is, the statement in question is was - "we talked about all the points/topics that we planned on In the seminars and interviews at the con."
The context of the statement is past tense. For it to not be static, WotC would have had to travel in time!
Come to think of it, that WotC had developed a time travel device, and were now engaged in temporal warfare with alien RPG companies from the future, might explain a lot....
