The 2020 International CES show will begin on Tuesday, January 7 and ends on Friday, January 10. And Sony will have its CES Press Conference on January 6th, 2020 at 5:00 EST. But I do not expect any new Sony Alpha gear on the CES 2020. My guess is we will see the Sony a7 IV at the CP+ show 2020 and the Sony a7S III at NAB show 2020 in April. You can watch the live stream here.
In addition, Panasonic will have its press conference on Monday, January 6th (10:00 – 10:45 am).
In addition, you can save some money on the Sandisk memory cards at B&H (48 hours limited).
