But I also would not be surprised if that eventually gets pushed out to "if you want that, get a bus mastering 65816 expansion card".

Well, as long as they give it a chance, I'll be satisfied. The 65816 used to be a huge deal for me given the better high level language support, but the situation with the 65C02 has gotten better in only a few months, so I won't die if they don't use the 65816.

Since the bus timings are tight, it really would be premature to check until they have a board working with the hardware they are going to use at 8MHz.

Thought I’d seen a plug-in replacement board somewhere, bit like the old 65c802 which I think isn’t available, which would give many advantages outside the flat memory

Yeah, that would work for the CX16p ... but they haven't specified if the CX16c will have a socketed CPU, so across-model compatibility is at present uncertain. An expansion board would work with the CX16c and, if it has an expansion slot or block header to add one, the CX16e as well. Also, if it has it's own dedicated High RAM, it could have a mode to work as a coprocessor as well as a bus mastering mode to work as the main CPU.
