The proposed design puts the cargo on the inside of the V to maximize good views, and probably helps with logistics. I imagine the novelty of looking forward while flying is a selling point.

Fuel is on the inside edge. Cargo is behind the passenger compartments. You can see the cargo doors on the image.

What if the seats far from the axis of rotation faced sideways instead of forward? People don't seem to be as affected by pitch changes as they are by roll changes, probably because we are get a lot of exposure to pitch changes whenever we drive in a hilly area.

The problem is the amount of vertical movement which will be the same regardless of seat orientation. Passengers will feel sick.

The angular change is negligible in either case. The problem is you're ping-ponging vertically. For example, a 3 degree bank correction in an aircraft with a 70 meter wingspan will move each wingtip by 1.3 meters vertically.

In the picture, the passenger cabin appears to be using only 1/3 of the wingspan, so the vertical movement of the outermost passengers (in the last row) will be much smaller than the vertical movement of the wingtips.
A last row width of 25m is much wider than the 5m of a conventional aircraft, but much smaller than 70m.

What if we place lift-fans in these undesirable areas? One in the center of the V and two out in the wings. Basically, instead of banking the aerodynamic savings we spend it on hauling dead-weight associated with VTOL operation. That could kind of make sense.
Designers could reduce the problem to an extent by building a double deck passenger compartment and putting the baggage compartments out toward the wings, rather than the current standard design which places passengers on the upper level and bags on the lower level. But there are limits to how well that can scale. I'm skeptical that we'll ever see flying wing or blended wing body designs used for airliners. Cargo and military applications are probably more realistic.
