No inside information, but assuming Apple's suppliers can ship the parts in time for the new products to be assembled, I would be surprised if we don't see (1) one or more new Mac Mini models and (2) one or more new Mac Pro models, all exploiting the company's new hardware architecture, by early spring.
Well, it's neither a new Mac Mini or a new Mac Pro, but the "Mac Studio" desktop computer that has just been introduced would appear to be a very attractive replacement for the 2013 Mac Pro for both still and video post-processing, and even for the 2019 Mac Pro tower.
Almost as an aside, an Apple vice president said during today's product introduction "event" that a Mac Pro based on the new architecture will be introduced "another day" (presumably in May or June).
At the high end, the new Mac Studio machine should satisfy even the Hollywood special effects artists and neural network developers. As far as I can tell, a fully-loaded Mac Studio should compete reasonably well for most purposes with a $25K scientific workstation. (In case you weren't aware that you could spend $25K on a PC workstation, that's nothing. Check out

I suspect the product plan for the new Mac Pro means Apple either has yet another, more powerful, "system on a chip" in the works or the company management wants to offer an upgradeable tower that can accommodate future improvements in graphics technology.
