Were you really expecting much more?
Consider the following:
- Durango have been testing a lot, but even things that help performance and would be in demand (such as an alu +8mm chassis for the DEX210) have not been released yet.
- Previously released Durango evolutions have been updated cars, not totally overhauled cars.
- A lot of developments that recently became public (such as the 410 side-by-side saddle layout) are too recent to be implemented in a production car.
- With the competition recently (both in 2WD and 4WD), they can't afford to wait for 6 months with a new release if they want to retain their market share.
- Durango may well be able to earn more money by chopping developments into smaller evolutions.
That said, I do agree their anouncement and then the wait to an actual kit page makes big expectations. Also, it seems they're putting updates on the car that are not worth advertizing with... new ball studs and ball cups won't make someone switch to a V4 from another brand, it'll only keep Durango drivers at Durango.
