Not sure about a diesel option. This article doesn't mention it at all which is a bad sign if that is of interest. It does go into the platform change. Although current model came out in 2014 the platform is actually significantly older. This will be a big upgrade.

The third-gen X5 was introduced for the 2014 model year but its underpinnings are shared with the second-gen X5 on sale since the 2007 model year. This fourth-gen model, which we’re currently expecting to arrive in late 2017, as a 2018 model, won’t have anything in common with its predecessors.
Thanks for the update. Looks like there might be a diesel upgrade too:

I have no idea if these sites are credible.
I don't know how they can offer a diesel without significantly downpowering the vehicle to meet emission standards.
I may not know enough about the emissions control options used in North American versions of these cars.
But I would say this: it has hit the fan on diesel emssions. Really. Hit. The fan.
From everything I can gather from a non-specialist read, diesel technology for passenger cars is now terminal. It can't meet the air quality standards that are going to be required. In that the NOX standard can be met in the USA with urea technology & SCR, but it adds complexity and cost.
Given NOX levels in major European cities, diesel is likely dead there (although the European manufacturers will fight this tooth and nail, they won't be able to hold off forever-- it will simply accelerate the movement towards vehicles being restricted to zero emission vehicles (at the tailpipe)).
Given the air pollution issues in places like California and Colorado, I can't imagine this will stay off the the desk of American environmental control bodies and legislators for forever.
Americans have been significantly more hawkish on emission standards than Europe. In particular NOX. I can't imagine that that situation will reverse for long. And PM 2.5 is the new frontier in air pollution control-- and the medical evidence seems even worse than we had imagined.

“I'm sure the levels of particulate matter and nitrogen oxide as well would be much, much lower in European cities if they didn't have the incentives they had for diesel cars,” said Helotonio Carvalho, a molecular biologist at Brazil’s Federal University of Pernambuco, Recife. He added, “We are going in a direction where diesel cars probably won't have a place.” Carvalho has written in the medical journal The Lancet that 400,000 people died prematurely from all the various sources of air pollution in Europe in 2011. I asked him how many deaths can be attributed specifically to Europe’s elevated rate of diesels, relative to, for example, North America or to his native Brazil, where diesel passenger cars haven’t been allowed as a matter of policy. He told me that the number is in the “hundreds of thousands.

Health experts lambast ‘deceitful’ carmakers as data suggests 97% of vehicles fail to meet NOx emissions standards in real-world conditions

Some of the health risks of inhaling fine and ultrafine particles are well-established, such as asthma, lung cancer, and, most recently, heart disease. But a growing body of evidence suggests that exposure can also harm the brain, accelerating cognitive aging, and may even increase risk of Alzheimer’s disease and other forms of dementia.
So one is talking about being able to legally drive these things for 10-15 years, maybe. Which means depreciation and resale values will get hit a lot sooner.
