We've switched over to the STM32 series, with the STM32f105 installed on our current board.

They give you another factor of 10 in speed, and probably an additional factor of 10 in pain to program and work around the bugs. But they are great for low power usage and functionality, with up to three 1Msps ADCs, DMA to use that high sample rate, dual CAN bus, 32 bit single cycle multiply and hardware (multicycle) divide. The current one on our board is 72MHz, and we can switch to the new 120MHz clock ones if we ever need it.
