Looks like Paramount Pictures in LA hosted a promo event for the fans today (and probably media too), featuring vehicles, props and clips from the Last Knight movie.

So jealous of the Americans who were invited to attend... and I imagine that if BotCon still existed this year, this event might have been done later to coincide with it.
