There's a near-infinite list of possible MCU decaps/dumps to be hoped for, including some whose types haven't been dumped ever or in a very long time (a good number of LCD handheld games fall into this). One category that stands out due to recent work by Haze are the PICs used as sound MCUs in various Korean games and bootlegs (particularly of CPS1 games). On the MESS side, I helped determine that a lot of presently unemulated VTech laptops are based on M68HC05 globs that might be trojan-dumpable from the cartridge slot. The long-stalled project to dump the Casio Loopy's CPU-internal ROM also comes to mind.
Probably my most important MCU-related plan is a state-level reimplementation of the MCS-51 (8051/8052) CPU core and standard peripherals. One of the smaller breakthroughs that will enable is getting sound communications working again on the MicroProse 3D games.
I'm also hoping that Angelo Salese will make enough progress on emulating the Seibu COP to make (non-bootleg) Seibu Cup Soccer at least semi-playable.
