I cannot believe that they are so far ahead in Ariya production that the chip shortage will not affect its release in some fashion. No one has yet commented on whether the 2021 release date will be for all states, or just selected ones (like the Hyundai Ioniq 5 {which will be released in 19 states in 2021 and the other 31 states in 2022.}). If Nissan does likewise, it is likely that the "initial state" release will not be affected much. But the full US rollout may be delayed for several months to a year.
