I'm still hoping the 6d2 has an improved DR like the 5d4 etc, I would be pretty shocked if it didnt. But its not looking good.
Its still a very usable tool but to ignore this aspect when they have the ability to address it is quite a large fuck you.
From what I understand, the on-chip ADC is what makes the biggest difference, and *was* what held Canon back for over a decade. Now that ADC is on-chip, we can expect them to eventually catch / surpass Sony / Nikon base ISO DR, I suspect. However Nikon / Sony has had well over a decade to perfect their banding-free shadows and on-chip ADC, so it won't happen for Canon overnight.
The 80D and 1DX2 were the first two cameras to have it, IIRC, and both exhibited a noticeable bump in base ISO DR. the 5DsR, in contrast, did not have on-chip ADC, and suffers the same lack of DR as always. The 5D4 and the other newer Canon Rebel etc. sensors all show significant incremental increases, and are beginning to approach the likes of the D810 / D750, but are still ~1 EV behind at ISO 100. The 6D2, unfortunately, will not beat the 5D4, though it may come close, which means that we'll have to wait another generation or two before base ISO DR is truly phenomenal.
Maybe they're saving their biggest leap forward for the 5DsR mk2? I'm pretty sure they could leave the MP count at 50, and just proclaim that it has industry-leading dynamic range at both base ISO and high ISO, ...and it would fly off the shelves just so long as their press release / early claims are proven true in early field testing...
I'm rooting for Canon, because I'd love to be able to just advise "pick whichever one feels right" to people who ask about which is best for landscape photography, but it appears the 6D2 is still only an incremental step forward towards that ultimate goal.
