How about licensing costs? ARM makes a pretty penny and I would still expect ARM cores to be more expensive than 6502.
Licensing costs could be a problem for ASIC development, which is where 6502 cores (or similar) would have an advantage. If you buy off-the-shelf ARM devices, like I do, the licensing cost would be rolled in the price of the device. In practice, these prices are quite competitive.
Seems Andes Technology has found the market ripe and is possibly snapping after ARM's lunch. They have been working for a few years and surfaced recently with a few licensable cores and systems.
http://www.andestech.com/en/index/index.htmI haven't found detailed descriptions of the ISA but what I find indicated 16, 32 and 64 bit features. It seems reasonable to assume these cores are bigger and more costly than 6502, yet the Andes devices are in part promoted as 8 bit alternatives. So there should be still a lot of life left in the 6502 a a commercially used core.
