Would imagine so, plus the chips are probably a fair bit harder to come by than 030's.
I'm guessing the 25mhz-40mhz 030's must be easy to get in good volumes which paves the way for occasional 50mhz boards when those cpu's can be sourced. Might be a different story altogether to do an 040 board if the even the slowest 040 chips are going to be hard to come by.
