Only thing is Dave, it's not yet been confirmed that it'll definitely take place at Sywell (if indeed at all).
There was some speculation when Duxford released their airshow dates for this year that it may return there, though no word since.
Tentative conclusion being that this year's announced IWM-run dates are June, August, September and October, leaving the July dates either free for TFC to take or so as not to clash if at Sywell.
Admittedly the latter is most likely, but TFC have been unusually quiet so far. Also, just happened across this recent discussion. https://forums.airshows.co.uk/viewtopic.php?t=86930 TEXANTOMCAT helps run the museum at Sywell and is usually quite well informed.
