The V-280 design is evolving as it moves towards EMD and then production. As this process is still dynamic, it's probably too expensive to keep updating the mockup until the design is frozen. However, keeping smaller models current is doable. This is a model of the V-280 design as it appeared earlier in 2024. I'm a little surprised the model apparently wasn't at Farnborough since you can see the mockup was at the show where the updated model was unveiled. Some of the changes we can see are in the nose and forward fuselage as well as the side doors, and apparently a refueling probe may now be standard.
