It would be stupid to announce FFP the same day as a $350 single day ticket. Us super fans already know they get released in July so we know they're coming, some of us (judging by recent posts) will still bite on the new up charge ticket, and for the general public who are looking to check it out for the first time or are from out of town seeing single day tickets as much as $200+ then this option with food, drinks, free parking, and swag included for only $350 will be tempted to bite.
You throw a $250 RoF ticket into the mix at the same time, that's good for every day in September, it makes it much harder to generate "impulse buys" of $350 for a single night.
Edit to add.... ^^ are you going to post that same GIF multiple times a day until it's announced? It's getting reaaaaaally annoying.
