Does XDMA = better Hybrid Crossfire?

Video Cards and Graphics - AnandTech Forums - forums.anandtech.com
From Anandtech's 290X review:

Quote:

Ultimately AMD?s goal with the XDMA engine is to make PCIe based Crossfire just as efficient, performant, and compatible as CFBI based Crossfire, and despite the initial concerns we had over the use of the PCIe bus, based on our test results AMD appears to have delivered on their promises.

Dual Graphics has always used PCIe to get the frames between the GPU and the APU. Does the addition of an XDMA in GCN1.1 mean we're going to see better Dual Graphics? (Because let's face it, it was a complete disaster before now.) Kaveri plus a Bonaire chip could be an interesting combination.
