Sadly they aren't continuing Microsoft's Surface Arc Mouse. As far as I know this is the only non-Apple mouse with a scroll surface, and not a physical scroll wheel.
Apple's patent on touch sensitive mice (8279176B2) doesn't expire until 2026.
One day physical scroll wheels will be a thing of the past.
The Wedge Touch Mouse, which has a weird wedge shape and runs out of a single AA battery also has touch sensitive (vertical only IIRC? haven’t used it in a while) scroll as far as I can tell.
I can't edit my post anymore but since this was downvoted I want to elaborate that I meant this seriously. I wash my hands before using my computer, and my peripherals don't get dirty. I also don't eat at my computer desk.
