I see what you mean. I'm pretty sure the last "Note" was the 20 Ultra, and from now on it will be part of the S series, but we will have to wait and see what they say on the 9th of February.
I'm not a fan of folds and flips, I was never tempted to buy one. I think they still have some way to go.
Contracts are too complicated for me, I always buy my phones contract-free, directly from Samsung ☺️
