Elite’s announcement is at Elite
Interestingly, there’s now an “Elite Cog” version of the Cog with an 18-tooth sprocket instead of 14-tooth - see Zwift Cog & Click | Smart Trainer Upgrade | Accessories
The new Elite Cog is surely designed to overcome the known issue of the Direto XR (don’t know about other Elite trainers) having a slightly higher base resistance than many other trainers which leads to not being able to set low enough gears to do high cadence with low power (on the flat). This seems like big news.
