There’s been no official announcement yet and they don’t seem don’t appear to be listed on the Godox website (at least not publicly), it looks like Godox definitely plans to release the V850III and V860III speedlights this year. We’ve been sent a couple of screenshots, purportedly from the Godox 2021 catalogue, showing the new Godox V860III and V850III speedlights.
The source that sent us the screenshots say that they’ve been added to the 2021 catalogue and they both include some nice changes from their V850II and V860II predecessors. The V860III sees the same locking foot lever as found on the V1 and it gets a modelling light. Both models see UI changes and a switch to a new battery – the same one as the Godox V1.
