This is likely one of the most unexciting camera updates ever. Nikon announced the new D810 (specs at Amazon) which features the Sony 36MP sensor and brings only very minor improvements over the D800 (electronic first curtain and so on). The news that matter for us are:
1) There is no new Sony FF sensor in use with the camera. This is the same A7r sensor. Don’t know if that means that Nikon has no exclusivity on new Sony sensors anymore…
2) This may be a chance for Sony to close the gap with their new A-mount FF that could be announced at Photokina in September.
It will be far more intersting to se what Canon is up with their new FF sensor tech. Going to be an exciting rumor summer :)
