Actually, it doesn't look a "totally new" to me. I believe it's
flapped as

kestrell19 said, so it propably has a little different airfoil, at least
at
the flapped part, but the wing shape still looks the same,
multi-trapezoidal
wing, as in DUO.

the fuselage is similar to XL (new - longer fuselage Duo/Nimbus
fuselage)
However - it can be equipped with an electric self launcher so is
structurally somewhat different...

And that's a good point. Looks like the electric propulsion becomes a
new
trend for powered sailplanes, and I think it *is going to stay there for
much longer than the little jets. But still, couldn't they just give
DUO
the
battery, leaving the DUO name (same fuselage, maybe the elevator...)?
Perhaps, when they show some more specific technical info and more
detailed
pictures, I will change my mind.

The wing certainly looks different to me. *I have just compared it with
several photos I have of DUOs.
