Like teams are going to be privy to other team's designs. Some components will have been made and the chassis manufacturing started (maybe already at the crash-test stage), but the people responsible for them will be at the factory and would be highly unlikely to be in Abu Dhabi at any stage (other than tiny teams like Haas perhaps). Designers certainly wouldn't be bragging this early either.There was some paddock talk and whispers in Abu Dhabi that two teams had supposedly found a loophole and had come up with something performance boosting that other teams didn’t have. Of course nothing concrete nor who started the rumour or which two teams had found the mystery item/design.
I suspect it's just someone predicting that two teams will have ideas others haven't thought of.
Unless Spygate II is on the cards, this time with sticky fingers on two team's designs and openly admitting it.
