I'm not sure they could do much on the fold 8 to give me a huge wow factor. Most yearly upgrades don't, but going to the fold 7 from the fold 6 was a significant upgrade. Main reason I upgrade yearly on the folds are the inside screen, less chance of issues, the inside screen protectors seem to start lifting on center of screen at the fold. I will say there seems to be less worry on the screen protector bubbling on the fold 7.
I'm going to look at the 8 wide, but I'm not sure I will like the smaller format when closed. If I do upgrade this summer, I'll probably pre-order both the fold 8 and 8 wide. I'll go look at it at a best buy and cancel one or both of the pre-orders. The fold 7 is a hard phone to leave.
I will edit this to say if the fold 8 series have screen privacy, that will probably get me.
