Well, I don't see this happening (G5 support) in the next release alongsidr X5000 support (IF we even get that).
And 3.11 is likely to be a 'bug fix' release.
Also, they have not stated that support for the 11,2 was even under consideration.
I bought mine to run Linux, to have something to compare the X5000 to, because it's about the best PPC system released for single user applications, and on the off chance the support might happen.
But if it doesn't, I still have a competent PPC Linux system.
I don't know personally how valid the complaints about the X5000 are, but the expansion bus of the 970MP has a LOT of PCI-E lanes.
