My thoughts on this are the exact same as they were last year when Ice universe said the same thing That the Note 10+ was the last Note. The Note is most likely going away in name only. Whether that means merging the Note and Fold or the Note and Ultra version of the S series, or both. Having a Fold with SPen and an S series with SPen could work. I could definitely see Samsung keeping its end of the year release to foldables and the earlier release the S line (with the Ultra incorporating the SPen). I said then that it would peeve whomever bought the Note that year off releasing one 6 months later under a different name, but it'd be a single release change, and that people would get over it.
What has changed a little though are my thoughts on the timetable. I thought it'd still be further down the road when the foldables were a little more polished that all this would happen. But Samsung improved the Fold 2 so much over the original that maybe this could be the year.
