My guess would be these are "payday" festival appearances to make sure the tour crew are covered whilst they aren't touring for most of the year and onwards into their usual "hiatus". They've done this in the past years, either taking high paying festival offers or private/special booking shows. Like those in NOLA, FF have clearly been paid handsomely for those, going by the ticket prices.

As such, I personally wouldn't expect any big Foo headline shows announced, but you never know of course. I guess small warmups aren't out of the question.

Also for these twin festivals specifically, they were presumably outbid by Rock Am/Im this year.
