Maybe you right. I've seen low light footage and A3 beats Mini3P.The A3 does not have the same sensor as the Mini3P.
As a result, there's been some crow dinners consumed post-release from those claiming A3 inferior quality to the A2S and the M3C based on sensor size alone.
I don't have an A3 yet for comparison. However from the reviews I've seen (YT) and read, it looks like the majority opinion is A3 beats A2S and is about a wash with the M3C, depending on what's important for the image.
The computational image guys have continued to improve compensating for the larger errors in color channel reconstruction from quad-bayer filters. The clean, detailed 48MP images the sensor + GPU in the A3 are producing unexpected superb results.
Still, at least for photography, the M3C' 20mp camera seems to be the better option at this time.
It is the extra zoom camera that should be the decisive factor for replacing M3C for A3.
As for the Occusync 4, personally I'd prefer wait for the Mini 4 to get into that.
