Yep i think thats why even POWER isnt sold standalone but as part of the Z/i series packages as a unit.

They will probably market the ARM inclusion similarly - as something that the package provides.

As far as POWER i think only Raptor[1] does direct marketingof the power(hehe) and capabilities

POWER is sold standalone, it's not packaged with Z.

The i systems are just POWER machines with different firmware.
