Seems like maybe it could begin with the Fold 7, but actually stretch onwards to their other products (namely the Tabs). I swear I came across an article somewhere else suggesting it could somehow be based off AES, but it wasn't going to need a battery. It's like they were going to pull off what XP-Pen and Huion did AFAIK -- more or less an EMR experience without licensing Wacom.
Part of me would be really interested in them moving away from Wacom UD onto something new, but the other part is apprehensive. I've had moments where I became frustrated trying to find a UD pen that works for me, and during those times I'll start thinking UD mediocre, but right now I'm having a fantastic experience on a T10 Ultra with a Mars Lumograph.
If Wacom can't get licensing money anymore from Samsung (assuming it's a fair chunk of change), maybe they'll make an effort to go back into Pro-EMR TPCs. To be frank, I kind of thought it was a joke that the Movink was just a pen display. Let's say they are a company that is barely scraping by, which could very well be true: If nothing else, maybe it's a good time to release a vanilla Android TPC if it's too expensive to be a Windows OEM. Maybe they could almost strike gold by releasing a successor to the Cintiq Companion Hybrid, which seemed to be way before its time. Who knows.
I regularly bounce between the M4 Ipad Pro with Apple Pencil Pro, Surface Pro 11 with Slim Pen 2, and the Galaxy Tab S8+ with the Zbook X2 Pen (with grey nib), and a 16-inch XP Pen EMR device. Of the 4, I would still rate the Tab S8 as the best pen experience by far.
If Samsung were to switch, it would have to be AES. I honestly wouldn't mind that, so long as they can fix the crease once and for all. On my Fold 5, I hardly ever use the pen because of that damn crease. The physical dip in the screen it creates annoys me to no end. And I'm already using the Bluetooth-less Spen, so I'm already missing those features. If they could eliminate the crease/dip entirely I would adapt to AES.
Have to disagree with the Movink, that's probably the most interesting product Wacom has released since the Cintiq Companions. And for those purely looking for Desktop solutions, its a great price for an OLED screen. If it was a tad larger at 16-inchs I might have bought one, but opted for a XP-Pen display that works fine for my needs.
