I think they will add the PH option for the FP+. I think they could give you 4, maybe even 5 FP+(if we're very lucky, lol), but they could still limit you to the tiers that are in place now. They could also limit you to 3 at most in one park in a day, like now, and then the other 1 or 2 would have to be used in a hopped to park, all following the park's tiers. They could even limit that 1 or 2 to only a second hopped to park, so you could hop all you want but only have FP+ in 2 parks, with 3 in one park and the other 1 or 2 in the other park you choose. That would still help limit the headliner grab a little but increase the value of park hopping compared to now with no fp+ for the second park if you hop. Right now, you can get any 3 you want at MK since there are no tiers. If that's the park you use 3 in, you can get still get another headliner when hopping, but will be limited by the particular park's tiers, so it's not wildy using the extras on all headliners - just one more headliner at most if you hop. Might encourage more hopping and getting guests to spend that extra $60, and encourage guests to still stay on Disney property when done with one park for the day. To me, this makes a lot of sense!
