Best guesses are sometime around March, but those are just guesses -- until Apple announces a date, or just releases it, no one knows. I've installed it -- and so far it's been issue free, Bluetooth keyboard support is great. The handful of apps I regularly use are on the Top-Shelf or in the few rows beneath, so folders are not a huge deal for me -- not even sure yet whether I prefer them or not. I find that if I want to launch an app I don't use all that much, Siri is the way to go -- certainly faster than navigating to a folder, opening it, navigating to the app and selecting it... 😵
