Top-end TRX40 is around $1000 (Zenith II). That's almost double of Zenith Extreme x399; x399 had 16-phase VRMs as well in later releases; PCIe 4's usefulness is questionable (basically just for 100 Gigabit networking right now).

For x399 users TRX40 is underwhelming as it just feels like "pay for the same stuff again" if you want to use new CPUs.

Halo boards are always stupidly overpriced. X570 tops out at $1000, too. That's a terrible way to judge a platform's costs.

Not true at all. It's more bandwidth to the chipset, meaning you can run double the PCI 3.0 gear off of that chipset than you could before without hitting a bottleneck (well actually 4x since the number of lanes to the chipset also doubled...). That means more SATA ports. More M.2 drives. More USB 3.2 gen 2x2.

Not disagreeing on that but that's very different from TRX4 is "overpriced vs X399." Just because it's not worth upgrading to the new platform doesn't make the new platform overpriced vs. the old one.

Not necessarily the case in practice since that would require some sort of chipset or active converter exposed by the motherboard to mux 3.0 lanes to bifurcated 4.0 lanes. A 3.0 x4 device still needs those four lanes to get full speed so in a PCI-e 4.0 setting you’ll actually be using up four of the PCIe 4.0 lanes, but inefficiently.
