That's completely irrelevant ... go further down in the article and read the section headed:
Table of sensor formats and sizes
That explains where the size names come from and that they have no relation to the physical size of the sensors.
100 'effective' MP camera, whatever that means. So, is the file size the same as my Fuji GFX 100MP medium format camera? Does '1/1.3" sensor size' mean that it is actually a 1" x 1.3" rectangle? They are going to pack 100 MP into that space? Good...
