Nikon has marked the calendar for when it will introduce the next generation of its full-frame mirrorless cameras. The company created a splash page counting down "the next chapter" in its Z series, which will be announced on October 14th at 12AM EDT. 

Both the Nikon Z7 and Z6 will receive a facelift, but to what extent is somewhat unknown. Will we see Nikon try to make a leap in resolution or will it be more of a favorable upgrade designed around user functionality similar to the Sony a7S III?

Purely speculation, but at the very least, we suspect Nikon to include external ProRes RAW without needing to upgrade the camera like we've seen in the Z7 and Z6. But what else? Maybe an improved autofocus system? Better low-light performance, IBIS, and overall image quality? Possibly both cameras will receive 4K at 120p, but Nikon might limit the Z6 II and save that for the Z7 II. Here's hoping they don't. 

What do you think will be part of the new mirrorless cameras? Let us know in the comments below.
