This morning I had a look at Google Patents, and there are 3 recent Meopta patents that may give an idea as to what a new B2 could include . . .
a) USD904480S
Shows a new external design for a binocular:

(there are more images in the patent)
b) US11474338B2
Features a focus mechanism where the user can alter the amount of focuser resistance:

c) US11372193B2
More unusually, features a focus mechanism where the user can electronically record preferred default focus distance(s) [by pressing the button 4],
to allow rapid refocusing between objects at different distances [a set distance being indicated by the LED 6]:
