Phone innovation is indeed dead -for the customer, that's ok, but for the vendors it's a nightmare.
I don't know much about Royole, but Huawei's foldable comes from BOE and BOE is many years behind Samsung both in mobile OLED and foldable. BOE is accused of copying/stealing Samsung display tech.
I still want a compact flagship phone.
It's going to be a phone with a huge, heavy battery, or a weak laptop with very short battery life. Running a limited phone OS or a heavy laptop OS. You'll have to open your phone to use it, and close your laptop to take a phonecall unless you also have a headset and are close.
This is as gimmicky as anything, possibly pending the arrival of magical graphene technology.
It is a gimmick, albeit a more useful one - have tablet and phone in 1 device. The thing is, tablets for most folks are not that great thing that everybody though they would be.
I don't see many people these days using tablets, most folks went back to phones which can do exactly the same stuff. For reading books kindle et al are much better (and cheap) product. People upgrade phones more often, and who wants to use sluggish oldish tablet compared to blazing fast phone that is always in the pocket.
