Looking at the S21 Ultra, it does not have an expandable SD card slot, doesn't come with a stylus (will support a stylus though) and there is no stylus housing built into the phone itself. Seems like they are making a lower Note capable phone rather than a full on replacement.
DunnoSo is the Tweet saying the N21 is the last Note?? Or the N20 is the last Note??
I'll wait on Samsung's announcement.
Another answer that doesn't really answer. These corps are as good at spin and double talk as politicians.Phone arena reached out to Samsung and their response is in this article.

I use the pen a lot and having to buy a case just to hold the pen is not going to fly for me.
I will keep my note 20.
