Rick has pretty much covered this in other threads and also shot down "they can't do <insert game name here> because of the licenses".
Before the MMR announcement, the official stance was "We have not announced a remake of Medieval Madness".
Nothing has changed - until PPS makes an announcement to the contrary, assume they could remake any B/W title they want. All the speculation about what they might do when does absolutely nothing except create more threads to beat the same dead horses to death again.
Nobody knows - and nobody will - before Rick makes the next announcement.
