Which means this is a whole new chip. It may be M3 based, but with added interposer support and new thunderbolt stuff.

Which, at this point, why not just use M4 as a base?

I imagine that making those chips is quite a bit more involved than just taking the files for M3 Max, and copy-pasting them twice into a new project.

I imagine it just takes more time to design/verify/produce them; especially given they're not selling very many of them, so they're probably not super-high-priority projects.

Could be that M4 requires a different TSMC fab that is at full production doing iPhones.

Or they are saving the M4 Ultra name for later on ...
