Assume they had a finalized design for M2 at the same time as M1. If their plan was to produce and roll out machines based on M2 shortly after the release of M1 they likely were not able to do it as planned due to COVID bottlenecks. Almost every company that produces physical products had to focus their resources on producing high volume parts. This has happened quite a bit in trailer manufacturing for example. All of the raw materials are going towards high volume selling trailer models. Niche trailers models are not being made in any significant quantity.
