1: No 100hz lottery anymore
Until proven wrong, the monitor is a 100hz out of the box. This means ASUS is doing all the overclocking, and they'll most probably make sure all the panels reach that refresh rate. That's one less problem when comparing with the X34, which comes as a 60hz monitor, and struggles to reach 100hz for most users.
2: They're taking their time before releasing it
One may disagree with this, and I'm totally OK with it, but the PG348Q was announced long ago, and only now it's about to be released. They had plenty of time to make it work properly, enough time to even see their competitor's issues and manage to fix them. Also I've heard that the last Swift monitor had many problems as well, so that's one more reason for them to make things right this time.
EDIT: Just to be clear, I'm not an ASUS fanboy, neither had any recent products from them. But after reading about this and doing some research, this is what I've concluded. I really want this monitor to not be a failure, because I think 21:9 is the way to go and should become a standart in a near future (much better than that 4k gimmick), and for people like me, that will have to import such monitor and pay around 2K for it, it's better be working flawlessly. It all depends on ASUS. Fingers crossed!
