I've been thinking about this for a while.
With smeargle and delibird both needing special features regarding the gyms, niantic is obviously going to try their hardest to be able to fit in those mechanics to the rework. (Unless of course they don't want them in the game, but I HIGHLY doubt it).
Do you guys reckon they might release them on the rework update? It makes sense to me and tbh I could really see it working out to defiantly revive the game for a bit longer. I would love to see both of them in the game. I haven't seen many people comment on the release of it either.
