I've long been a fan of the NC concept and
ran a 2018 750X for a month last year with a view of adapting it to an all-road travel bike. (Did it to an XSR7 with reasonable success).
Great road bike, loves to corner, all the real-world power you need, showed 100mpg at times and basic suspension was prerty good. But for many obvious reasons it was too hard/costly to adapt.
I've mentioned here and there WLT see a properly 'adventurised' NC750X.
Looks like they're doing just that. It's such a nicer motor than the equally economical CB500X.
Fyi, the engine pictured in the MCN mockup picture looks like a CB500X, not the distinctive slopping NC.
Thing is, NC may be low CoG compared to my current AT, but as FF says, it will still be heavy (weighed mine - a DCT: 232kg).
So it won't be a contender against a T7 let alone a 790, but from what MCN says they're pitching it as a budget A2 learner bike with adv looks, as with most Jap bikes in that style.
wrt fuel tank access, I think what ChrisJ meant was the faff of lifting the rear seat to get to the filler cap. The rear-tank BMs have the filler to the side. I know it's only similar to unzipping a tank bag, but Honda would do well to copy the BM idea.
I'd sooner have the fuel there and keep the frunk. The tank's modest 14-L volume/weight gets you well over 400km.
