Given that they had to upgrade to a new camera sensor to get faster readout speed, I’m wondering if they actually changed to a better sensor with improved pixel size and light sensitivity.
I have read the official press release but it seems like there is no mentions of this.
Might need to wait for the ifixit tear down in ~10 days.
Edit 1: there has been some discussions that eventually the Sony IMX903 would be used, but not sure when that will actually eventuate.
