Q3 according to latest leaks likely will not have OLED microdisplays. More likely they are going to be miniLED like Cambria. Cambria 2 is the one that will have OLED microdisplays, and it will come out a year after Apple's headset, or maybe sooner/later depending on how many delays Apple/Meta face. That is also around the time Valve might possibly release their new headset.

Maybe. There hasn't been any info yet on whether Q3 will use Cambria-type controllers, or keep Constellation to save on cost, since it's the budget headset, not high end.
