Nikon Corp are very tight lipped about what is about to appear, there are people who know, but they are obliged to sign non disclosure agreements.
No one will tell you anything until the day that those who need to no are informed, Canon are just the same..
There have been leaks in the past and from personal knowledge I would not like to be involved..
When it comes, whatever it is you will be told,, they are so tight lipped it is frightening
Enjoy what ever comes when it comes and buy now.
There are so many people in the world who say that they have heard of this and that coming and it does'nt..They will never ever buy a camera because they are frightened of their own shadow..
