In addition to the Sigma EVF-11 external electronic viewfinder, there are two other new products from Fujifilm and Sony registered online:
Fujifilm has a new battery NP-70S (3.6V, 680mAh) - most likely a replacement for the current NP-70 battery used on Finepix cameras.
Sony has a new wireless microphone ECM-W2BT that recently passed FCC certification. The scheduled release date is March 1, 2021.
