ARM being a good idea doesn't mean it would have worked for AMD

Looking at the timelines on K12 and the consoles, it looks like K12 early design work began at about the same time as AMD won the console bids for PlayStation 4 and XBox One. It would thus seem plausible to me that K12 was also about hedging their bets if Microsoft and Sony (who had not been tied to an ISA in previous generations) started looking seriously at ARM-based competitors for the XBox Series X and PlayStation 5 generation of consoles. At least with a decent ARM core, if you hear that the decision is ARM, then you can still bid - albeit now competing with many ARM ecosystem chips.

Once it becomes clear that Zen + RDNA will be competitive for the next generation against any ARM ecosystem chip, then AMD don't need K12 for a future console bid - they can stick with x86 and beat the competition. At that point, they don't need the ARM core, so might as well scrap it.
