Gravity will be based on a completely new platform from Air.
Pros: Built specifically for EV SUV.
Concerns: Increased complexity. Potential production ramp up issues vs ramp up with a production proven platform based on Air. Increased costs, less profits due to less parts sharing. Increased costs, less profits due to separate development costs.
Obsolescence for Air.
Concerns: Gravity will have more space, better tech, better UX, more luxurious amenities, air suspensions, etc. but in the similar cost range as Air. Why buy an iPhone 14 Pro, when you can buy an iPhone 15 Pro Max (why buy a last generation car)?
Management of different, but related UX systems.
Concerns: The Gravity and Air will use different UX systems. Potential new UX rollout may be problematic, it took a year after initial release for the Air's UX to become useable. Focus currently is on the Gravity's UX with some trickle down to Air's UX, how will management of work on each UX be divided?
Rollout and rampup
Concerns: Air released the most expensive models first, and took too long to ramp up to the less expensive models. Because of this rollout and rampup strategy, most Touring/Pure reservationists cancelled, and most future prospective consumers still think the Air starts at $159k instead of $77.4k (most reviewers only had the $159k GT or $179k GT-P).
