Just over the past month it's been like 5-6 announcement in the regards. I never saw that much activity before, hopefully economic context only improve from now on and most goes on to carve their place. I would love for MS to announce a new studio themselves even though the last was not so long ago with World's Edge in 2019.
Eh, I would still consider The Initiative as the last new actual studio. World's Edge are just caretakers of the Age of Empires IP. And they're doing a damn good job at it!
At least the latest rumors are that development of Perfect Dark is going extremely well.
