One thing I don't know is where did Nikon get IBIS tech?
It's not rocket science, it's been around for possibly 10-15 years.
So why did they never put it on any DSLRs before like Pentax were doing, why now?
"Canon &
Nikon say that OIS is better than IBIS, because:
- With OIS, each lens is optimally tuned to achieve reliable correction.
- OIS allows faster and more accurate AF & exposure metering, because the image comes already stabilized to the camera sensor (an advantage you’ll notice especially in low light).
- OIS is more effective with long telephoto lenses"

And the REAL REASON (Canon/Nikon) says OIS is better ...
THEY DIDN'T HAVE IT !!!
I doubt it. IBIS is not a complex technology, and they are both companies that produce semiconductor lithography equipment, which includes active stabilisation and correction which is hugely more tricky and complex than consumer still camera stabilisation.
The truth of the matter is most likely in corporate culture. People seem to think that cameras are designed by automata. They aren't, they are designed by people and people have belief systems and cultural attachments. Any engineering organisation builds up its own way of doing things. You can see thins in other products too. So, for instance, BMW cars always have old-fashioned rear-wheel drive. Most other manufacturers use front-wheel drive. Why is that? BMW design culture has led their engineers to believe that RWD is a better solution for the type of cars they are building (and car fans will argue forever about it).
The same is true in cameras. There are arguments in favour of both lens and body stabilisation and different engineering teams have developed their own ethos. The prime example is Sony, where the Sony team were proponents of lens stabilisation and the imported Minolta engineers were proponents of body stabilisation. When the Minolta team was given the FF A series they designed in body stabilisation because that's what they believed in. The Sony team designed APS-C cameras have only just adopted body stabilisation.
So far as Niko was concerned, I guess what happened is their marketing people realised that the Z series had to have body stabilisation to compete with Sony, so they put it in even though their engineers likely believed that lens was better. It also make sense because it allows the lenses - which they need to develop a lot of, fast - to be simpler. Now they have a plug-in IBIS, it makes a whole load of marketing sense to put it in the D6. Two reasons. First, it's a feature Canon doesn't have (although let's see when the 1D X III is announced) and second, Nikon's lens line up has a deficiency in stabilised wide options compared to Canon. IBIS allows Nikon to address that without introducing a whole load of DSLR lenses, which they probably don't want to do.
