The code verification chains for the three popular consoles have been cracked repeatedly.

Sorry, but no. Only Wii (which apparently had security bolted on after the initial design) can be broken using only software without any specialized hardware.

XBox360 does not have any software exploits: all the existing break-ins require hardware modifications.

PS3 was only broken once, that happened half-year after removal of OtherOS and was quickly and efficiently remotely patched: if you ever upgrade your PS3 to firmware version 3.56 you'll lose the ability to break the code verification chain. The time where you had the ability to use PSN on cracked console was short indeed.

One of the obstacles to disassembling and finding weaknesses in the code verification chain seems to have been that the relevant code has been embedded within ASICs and/or encrypted.

Right - this is natural next step. This will happen eventually. Actually this is already true for ARM devices (they usually are built as a single SOC with many different chips tied together) - perhaps this is why Microsoft is more concerned about them? It knows x86 will be crackable for a few more years anyway...
