If the Note 9 looks like the Note 8, would you be disappointed?
But is this a bad thing? Thin-bezeled smartphones still feel pretty futuristic and Samsung's curved Infinity Displays (a.k.a. Edge screens) are still very pretty to look at and rarely replicated by the competition. Yea, a new design would be nice but... where to? The Note 8 already has non-existant side bezels and super-thin "forehead and chin".
On the other hand, of course, if you are a fan that upgrades their $900+ smartphone every year, you'd expect your favorite company to push the envelope and try and surprise you again and again.
