Crucial has updated site with new Mac Pro ram pricing

That's because of the type of memory. Apple's configuration would probably be 4x8 unbuffered. Ram in general has risen in price lately. Last year you could find 16GB kits for the 2012 macbooks pros for $95 on that site. Now it's $163. It's a commodity, and there's nothing you can do about that. Apple's pricing is usually designed to absorb market fluctuations in Apple's favor. Other oems do the same thing, but I don't expect Apple to go totally crazy here. They have to keep it somewhat sane on the other models due to restrictive soldering. On this one they will probably keep ram upgrade pricing somewhat aligned. I could definitely see +$400 to go to 32GB.
 
I still remember the good ol' days of Apple Ram costing more than the system itself. I think it was $5700 to configure 16gb of ram in the 2006 1,1 Mac Pro, when the system itself was $2499.
 
The Crucial site mentions that all lower density modules must be removed before installation, does anyone know if that's actually the case? It implies that you couldn't just swap two (or one for the 4-core) module with two 16gb ones to get 40gb, but would have to install four 16gb modules in a single go; i.e - no mixing and matching of sizes.

It depends on whether Apple are using RDIMMs for 4GB and 8GB modules. You can't mix them.

Performance wise unbuffered DIMMs would be the choice, but they don't come bigger than 8GB.

Apple clearly states "4 channel" memory, and Intel has usually required identical DIMMs in a channel (although sometime it's OK to have the same-sized DIMMs of different speeds - they'll all run at the slowest speed).

I would be surprised if Crucial's claim is not correct.

Intel require identical UDIMM/RDIMM combinations yes, that is why Crucial are saying it. Apple shipped 1GB, 2GB and 4GB UDIMMs and 8GB RDIMMs with the last Mac Pro so Crucial are probably just hedging their bets that 4GB and 8GB may be UDIMMs, or maybe they do know having asked Apple.
