In addition to the D820 and D7300 Nikon is rumored to announce five new Nikkor lenses this year (as of today Nikon still has two camera models that have already been registered with various government agencies but are not yet announced: N1546 and N1610).
The Nikon D750 replacement is rumored for late 2017 or early 2018.
It is still not clear what will be Nikon's future mirrorless solution and when it will be announced, but there is a good chance that nothing will happen anytime soon - at least not in 2017 (the pictures above are just design concepts by broxibear).
The future of the Nikon 1 is also not clear.
I still would like to think that Nikon will do something big for their 100th anniversary, but there is a possibility that we will only see the Nikon D5 and D500 limited editions sets.
Nikon is going through a major restructuring and I just think it will be a while until we see the results of it. Nikon even canceled their lens-only rebates they have been doing for years during the February-March timeframe.
Here again are some of the key points Nikon made regarding their future plans:
- This is a quote: "bringing in multiple mirrorless cameras at an early stage"
- In the future Nikon will concentrate their resources on mid-to-high-end DSLR and mirrorless cameras and lenses.
- Nikon will have fewer models in the future.
- Nikon still wants to develop a high-end compact camera.
