A cheaply made smartcard chip should be much easier to breach than the main SoC. Both because it's way simpler, older process silicon… and much more importantly because you have an external bus going to it. Now that the big consoles use semi-custom SoCs, their NUMBER ONE principle is to not trust anything that's off the main silicon die.

They either can do it and keeping it quiet or they can't. Or maybe it's too impractical. Show me one article where someone claims to have extracted a key from a proper, modern smartcard.
