The second-generation flash will be called the Yongnuo YN600EX-RT II. No technical details have been released yet — a teaser message on Sina Weibo, the Chinese microblogging site, says “stay tuned”.
There is not a lot to separate the YN968EX-RT from the YN600EX-RT in terms of features, other than the LED video lamp. So it will be interested to see how the YN600EX-RT II distinguishes itself.
This year, Canon updated their Speedlite 600EX-RT to the 600EX II-RT, which has slightly faster recycling times. The Canon flash is available now for $529 from Adorama, B&H Photo and other retailers. The Yongnuo YN600EX-RT is available from Adorama, B&H Photo and eBay for $114.
