That was something I hypothesized could be done prior to the PS4 launch.
There's no indication that this was done, so I guess the more conventional way of allocating work remains in play thus far.

There's a decent chance at that point that large chips like Einstein are going to have CPUs on them, so what does that mean as to having everything on the same die?

The pacing concerns in that article are related to the PC driver and DX runtime model.
The console versions should leave more discretion--and blame--to the software.
