There is no way Ford is going to downgrade the Raptor HP by downgrading from TTV6 to V8. Having a V8, TTV6, and SCV8 is extremely unlikely, but 20 times more likely than V8 and SC V8 lineup.
It depends on what's actually occurring in the refresh/upgrade. If the part that gets refreshed on the standard trims isn't shared on the Raptor (like bumpers) and/or is cosmetic and not an actual functional upgrade, then it seems likely the Raptor won't get that refreshed part. Also, it depends on volume of Raptors being made, whether connected parts would have to be updated, etc.
Headlights would be a good example for the previous generation. Standard trims got new headlights in the refresh, which also caused changes to related trim and the front grill. If Raptors got the same refresh, which they did not, then it would have caused completely different trim piece and grill, making it much less cost effective.
If the standard trims get a new larger infotainment screen, it seems likely that Raptor will too, as it's shared parts and keeping the old screen on Raptors will only result in increased costs.
