Difference between Video Doorbell 2nd gen and Video Doorbell 2

Hi, could someone please confirm the difference between Video Doorbell 2nd Generation (due 3rd June 2020) and Video Doorbell 2 (currently available)?

I want to buy the 2 but I need to make sure the corner kit for the “doorbell 2” is compatible with the “2nd generation” doorbell.
I just asked a similar question and hoping to find out ASAP.
