Don’t think anybody is saying that they will dress up the V4 as a retro. BH is indicating that the stubby rear end will be a modern take (like Duc and Beemer); straying from this current design trend would likely not sell. Norton will try and differentiate the rear end with the fin/lighting config we have seen.
I’d be (very) surprised if we don’t see modern retros in the lineup though - they are still a huge segment in the market and growing (apparently). With Norton’s heritage it would seem a ‘no brainer’.
My money’s with BT, the first will likely be a lower capacity bike to go head-to-head with volume models in that segment. Millennials like the classic styling, younger dudes the styling and lower cost.
Whatever they produce I’m really hoping they retain the original Norton logo - to modernise it would be a mistake IMO.
