I just assumed it meant that the Enterprise got another refit, allowing TOS and SNW to coexist properly. If SNW gets cancelled after s5 it can work! Everything can make sense!How so? Because they showed the New Jersey looking like TOS? That's an awfully big leap to think the visual aesthetic of Picard erases two shows from continuity.
They fixed the Klingons, anything is possible. I never lose hope. Well, sometimes I do, but then episodes like The Bounty happen and I get it back again.
