I wouldn't agree that RME should switch to VLSI.  I also wouldn't say it

is entirely fair to blame the cost on them using FPGAs.
FPGAs can be quite cheap.  Ignoring the mixer for a moment, the FPGA for

a 64 channel matrix + numerous input and output channels + high speed

link to other cards + PCI interface would be about about $15-20 in

quantities of one.  Expect discounts for 1000 units, and more discounts

for 10,000 units.
A VLSI would cost millions to make.  They might have to move 100,000

units using the exact same chip at the exact same card price to break

even, and if RME was that high volume of a vendor, then their FPGA

prices would be much lower than the list prices one can find online.
