The 13 inch MBP Ice Lake refresh will be interesting, but 15 inch laptops don't seem to have much on the immediate horizon.
But I don't think a new Intel CPU is going to hold this back. Even without drastically new CPUs from Intel, I could see Apple getting hold of some minor speed-bumped CPUs, much like they did for the 2019 13 inch MBPs and that would be enough.
There are then plenty of other upgrades they can shout about, the 16 inch screen in the same size chassis, a Navi GPU to drive the extra pixels, Wifi 6, bumping base storage to 512GB, 3000Mhz RAM. It's not revolutionary, but it keeps Apple in contention.
You might also see a slight curve ball like FaceID (although the TouchID still being present suggests not), possibly a cellular modem option given that Apple has picked up Intels 4G modem team, or the return of a discontinued port - my money would be on HDMI as it's not a legacy port, easy to add and they could sell HDMI 2.1 and Freesync / VRR compatibility.
All for a low low price!
Well, I can dream.
