Looking at the details listed from this leak, it looks like all the previous leaks were wrong. The specs for the main sensor are the same as the P7, the Samsung GN1 sensor.
Also rumors of the IMX787 ultrawide appear to be incorrect as well, only 48MP instead of 64.
It could make sense as a move to keep the cost down. It’s not a bad move given that the price is the same as last year’s despite inflation. The old sensors are absolutely great and they can probably keep them relevant for a little while longer given their Pixel 2-6a streak with the IMX363.
