I'd say we have something, at the conceptual level, directly from Boeing at Paris Air Show 2017
A bunch of concepts/goals with a similar but different rendering in the background:
A vague schedule:
Some verbiage about hybrid cross section and single aisle economics:
Perhaps the most intriguing design aspect of the NMA is the fuselage geometry. Boeing's early design studies have focused on optimising the cross-section to accommodate passengers, at the expense of creating space below-deck to carry bulk cargo pallets or containers.
The result is a hybrid cross-section for the fuselage, blending the passenger comfort of a twin-aisle on the main deck and the cargo compartment of a single-aisle below deck.
"It is a geometry that enables single aisle economics and twin-aisle comfort," says Delaney.

https://www.flightglobal.com/programmes ... 88.article is from 2019 with the new VP of marketing also at PAS:
"When you talk about the NMA value proposition, that is not a value proposition that addresses just the 757," said Boeing vice-president of commercial sales and marketing Ihssane Mounir at the Paris air show today. "It is a much broader proposition than the 757, in terms of market space, in terms of the capacity and the range it will address."
In any case, he argues, the A321XLR "addresses a sliver of that middle-of-the-market, and it addresses it with a single-aisle technology, with a single-aisle comfort, with a growth in weight of the platform that has been there for a while".
Mounir contrasts that with Boeing's vision of providing "twin-aisle comfort with single-aisle economics, leveraging new technologies, bringing a whole new airplane into the space". He draws an analogy with "the paradigm shift" that he says the US airframer achieved with its Dreamliner.
Seems the message did not change much from 2017 to 2019.
As I said, we also have interviews from airline executives given after they had been briefed by Boeing, so it's second hand info, but I think it's pretty trustworthy.
We don't know exactly what they were told, but we do know the DL CEO said he wanted to be the launch customer.
