Kuo: 'M3 Series MacBook Pro' to Be Focus of Apple's October 30 Event

I personally don't see why it would be awkward. The use case envisioned for the Vision Pro is probably not the same use case that people use the MacBook Pro for. It's hard to draw an analogy, but I can't imagine professionals and content creators will reach for the Vision Pro as the first choice for their performance intensive tasks such as video editing or whatnot. They will stick to the MacBook Pro, where that extra performance will be most valued. Moreover, especially with AMD and Intel's new chips, Apple needs to release the next generation of Apple Silicon to continue to be viewed as relevant by mainstream consumers.

Gruber seems to imply that Apple is effectively competing against themselves were they to release M3 chips before a M2 Vision Pro is released, however that assumes that the Vision Pro is intended to replace/act as an alternative to iMacs or MacBooks rather than more of a complementary member of the Apple ecosystem.
