I'm guessing the MBP13 is now a legacy model, being refreshed more to satisfy direct-product-line lease upgrades for corporate customers, than to satisfy consumer demand.
Along with the MBP16 refresh (which will use the "M1X", the higher-end chip), we'll probably see the higher-end MBP13s refreshed with said chip as well, but rebranded somehow, e.g. as the "MacBook Pro 14-inch" or something (as the rumors go: same size, but less screen bezel, and so more screen.)
And then, next year, you'll see MBP14 and MBP16 refreshes, while the MBP13 fades out.
These are transitional products so it makes sense. I'm looking forward to see the replacement of the iMac Pro and Mac Pro. Will be interesting to see what those include.
Addendum: just got an email from the Apple Store Business Team about the MBP13. Here's the copy they're using (emphasis mine):
> "Need a powerful tool for your business that’s compatible with your existing systems? Let’s talk. We’ll help you compare models and find the right Mac for you and your team."
That's a corporate-focused legacy-model refresh if I've ever seen one.
