Supposedly it was leaked from a conversation with some Blizzard devs that they’re currently working on Diablo 4 (which I think we already knew) and Overwatch 2 (which hadn’t been discussed before). Supposedly Overwatch 2 is going to feature more PvE content
It’s an attempt to salvage Overwatch’s appeal by making a sequel that doesn’t really do anything new or change any existing mechanics in the hopes that people will buy it because it’s new
All the while cancelling a potentially appealing StarCraft FPS game that could very much do well considering the nature of the game and its lore.
I think Blizzard thinks that by adding “2” it might be as good as Team Fortress 2.
