I'm not quite sure where he thinks theres a financial impact from those leaked pics. If anything it gave them a chance to fine tune somethings before unveiling the car to the public. Say people thought the taillights were horrific, this gave them some time to make corrections before publicly debuting it and have everyone say the same thing.
GM better do this car right cause they need a hit. And they better make the damn thing affordable too. If it's a mid $30's car they might as well scrap it right now and not even bother.
