Paizo doesn't need D&D any more, but I like the idea of a monster compedium for 5Ed with the creatures of Pathfinder.
Hasbro knows today the gold mines, the sources or incomes, are the franchises, the IPs. Today selling a product is easier if this is linked with some famous brand. And WotC isn't only selling collectable cards, but her mission is to create new franchises to be used by the rest of Hasbro team. WotC is creating new "pieces" to be parts of a "fantasy hasbroverse", let's say this would be a "WiztCoverse".
But the old franchises are as double edged weapons, with its pros and cons, the conflict between adding new things, because you can't be always telling the same story without changes, and the coherence with the previous continuity.
And now I think WotC isn't the main project because now Hasbro's priority is Disney/Marvel/Star War licencing. WotC's brands would be the plan B, or maybe the plan C after the cinematic hasbroverse (movies of Transformers, G.I.Joe, Rom spaceknight, M.A.S.K...). Part of this "plan C" would be the videogame adaptations. Let's imagine a Spelljammer/d20 Future version of Mass Effect, or a shooter based in Gamma World.
Hasbro is going to sell nothing, but maybe it wants to acquire some other company, for example a lesser 3PP, an indie videogame studio or even a film production company.
