Approximately how long would it take for a stable CyanogenMod release to surface? I can't find anything about this on XDA.
If I do end up using a Pixel, I'd like it to be rooted, and running CyanogenMod. What are your thoughts?
Well, usually it take around 3 to 4 month times for Cyanogen team to develop the ROM, since Android Nougat (7.0) just release few month back, so probably CyanogenMod 14 will be officially available by December.
But here's the thing, since Pixel came with Android 7.1, and Google just release the developer preview just a moment ago, I guess you will just have to wait until April or June next year for CM to officially release the CM14.1 for the Pixel.
Until then, just get a Pixel then, try it out first, I am sure you won't regret it.
