If one ignores the marketing hype (where wide roll-outs of high-split HSI with higher upload speeds will be seen real soon now), most expect only a few (smallish) locations by EoY 2022 (so Charter can say they started) to actually deploy and activate HSI high-split, and it taking (optimistically) 4 years to get mostly complete (when they will announce success, even as a number of people will still not be upgraded; sort of like the 200Mb/s HSI upgrade that Charter announced was "essentially" complete and then took 18+ months after that to get out to some locations). Clearing out the CableCARD and older STB users before they start extensive work in a location allows Charter much greater flexibility in schedules in the plant work itself, even if a lot of work is still to be done to actually activate high-split HSI, though, so that will typically happen quite some time before the HSI improvements.

Of course, at this point, it is likely that Charter is redirecting a lot of techs and equipment to the Florida area, which will certainly delay schedules elsewhere.

I am also in St Louis and have been receiving the Spectrum/Charter letters and emails about CableCards for the past couple of months. I just received a new letter by postal mail, stating that they will be adding new HD channels to my lineup "on or after Oct 6, 2022" which will be duplicates of existing SD channels.
The letter also states "NOTE: If you are using TiVo device series 1, 2, or 3, you will need to contact TiVo to upgrade to the newest series to avoid any disruption to your service".
So this seems like a new twist. No mention in this particular letter about dropping support for CableCards. I have a TiVo Premiere XL4, which is Series 4, so apparently I won't be affected by this change. But the possibly better news is that the letter seems to imply that perhaps CableCard support is no longer going away, at least for now?
