Yeah, sad. I'll wait for more info before updating. But for me, there is still no phone close to being as useful as the Duo. The other foldable phones (including Pixel) fundamentally don't work for me, because they don't fold open or support Tent mode. I know, they slap on an external screen as a bastardization of the Duo's elegant ability to fold all the way open, but it's no substitute and still misses tent mode or the ability to fold it around your hand to use in landscape mode (most stable way to game on a single screen phone).
I recognize I'm in a vanishing minority in my passion for the Duo, but my reasons remain valid for me personally. I really hope that someone (even if it's not MS) comes out with a phone that provides the key features that have come to matter most to me still unique to the Duo: automatic multitasking, wide form-factor displays (Pixel Fold may hit this one where Galaxy Fold does not) and ability to fold open. If that could be done with a single foldable screen (folding full 360 degrees), that would be even better than the Duo's 2 screen approach, but until then, I prefer 2 screens to 1 screen that only folds up to 180 degrees.
