You're so wrong it almost hurts. These monitors are basically a steal, and that's a very good thing, any way you slice it.
Really? they look like decent value at the current reduced prices, but if the price goes back up in January, no - this isn't any sort of "steal" unless, when the honest reviews come in, the display quality puts it in the top drawer of 4k displays.
The 4k model has very little "docking" capability: using USB-C means that (unavoidably) you can't provide USB 3.1 speeds on the same cable as 4k@60Hz video - so you're not going to be hanging hard drives or gigabit ethernet off it. Who knows what the speakers are like - given that the new MBPs are supposed to have pretty good speakers anyway (and we know from the iPads that Apple are good at small speakers). If you're going to need a hub/dock
as well then the advantages of this display over a cheaper, generic 4k display are nil.
The 5k model looks more hopeful - with TB3 bandwidth you could hang Gb ethernet and a backup drive or two off this - and the speakers are joined by a mic and webcam. Plus, there aren't a lot of 5k choices out there.
Deal breaker for me, on both, is the lack of any other video inputs - I have a ton of other equipment that I might want to connect to my "good" display from time to time - spare mac, linux box, PC, raspberry Pi - and virtually every other 3rd-party monitor has at least one other, switchable, input - including LG's other USB-C offering:

Otherwise, at least when the discount ends, what you have here is a third-party display, at Apple prices, with Apple-style gimped connectivity and
without Apple-style good looks. Feels like Apple dictated the specs and LG designed the box, which is exactly the wrong way round...
But this is so ugly. And the details are wrong. The forehead. The rear Power plus is in odd location off-center so cable drops down side versus behind the support pole. The thick tick support tube and ugly base. And the cheap plastic.
I'm telling myself that the "forehead" must be a mistake in what is almost inevitably a computer-rendered image of a product that isn't finished yet. Apart from that - I'd say its just unremarkable-looking.
I guess they've painted themselves into a corner by offering a choice of MacBook colours: black goes with anything.
Now, you may argue that they should have gone thunderbolt 3 like the 5K for $100 more, but this way it's compatible with the rMB.
If that's their thinking, its stupid. The rMB has survived for almost 2 years without an external display & is quite limited in what it can drive display-wise. Plus, the next refresh of the rMB will probably have Kaby Lake chips which, I believe, have TB3 on-chip, so it should have Thunderbolt.
TB3 would have made this more credible as a combined monitor/dock and justified the (undiscounted) price hike over regular 4k displays.
The other dumb move on both of these displays: only having USB-C output ports. Its not like these are ultra-thin devices, there's plenty of space for a USB-A port or two...
