They're already shipping it. It's as different from M32C as M32C is from M16C (m16c/60 at least) - no opcode compatibility at all, aside from a "passing resemblance" at the asm syntax level. M16C vs R8C is much closer; they differ only in two opcodes. M16C/80 vs M32C/80 have the same architecture, but m32c has more opcodes. RX is a step up from R32C. Same peripherals, basically, but completely different opcodes and register set.
