(SR2) Is this the new Sony A7sIII ?

CameraBeta just published a strange leak of what they claim is the new Sony A7s mark III. They got that image which they say lists the specs of the new Sony A7sIII:

– 15.4MP BSI-CMOS with LSI
– Variable IR Filter can be used as variable electronic ND filter
– Native ISO: 100-102400
– Maximum ISO: 409600
– 3” 1.23million dot articulating LCD screen
– 4:2:2 8bit 4K recording support

I don’t know CameraBeta and therefore I have to be very skeptical on this one…
