yes you are right, there will be no big impact unless something happens at this meeting. we'll see what Elon has to say about btc mining later. if he provides a good solution, it's possible that people will buy btc after the meeting.
Everyone will hope for good things at the meeting, but are you sure that Elon Musk will provide a good solution for mining? because usually rich people like him (Elon) always want profit for themselves without caring about the losses of others.
