Now that's an interesting project.

A micro-controller it will include on-chip memory and the pins on the chip will be I/O pins.
Maybe it's a bit too early to ask that sort of questions, but:
How much memory we are talking about ?
Since all of those three cores have their pros and cons:
Would it be possible to have all three retro cores up and running, or just only one core at a time ?
Would there be a mechanism for booting the cores from an external SPI EEPROM ?
Since page 10 of the slide "mentions" robotics, what peripherals are going to be in this microcontroller ?
BTW: please don't underestimate the effort required for having "nearly bug free" peripherals in a microcontroller.
One could, of course, just try to add sort of an 8031 core or such (which probably has some peripherals "included")...
"Customers" nowaday probably would insist to have Microcontrollers with USB and Ethernet connectivity integrated.
...Would be nice if the package of the chip won't be too impractical to solder for hobbyists.
