By what definition of viable ?
Hmm lets see:
Does PPC offer any roadmap by any current manufacturer for a general purpose PPC ISA processor that is even remotely competitive with even mid range x86?
No. Everything is being aimed at specialist markets - either high performance highly specialised stuff like Cell and Xenon for consoles, or SoC's based on the 603/604 that have been married up to any number of weird and wonderful kit.
The PA6T is currently the fastest PPC available, costs £450 (according to TD) and can barely compete with dual core x86 cpus that cost a tenth of that. Oh and there is nothing on the horizon that'll be coming out to top it due to lack of demand in the markets that PPC still exist in.
We already have an amiga OS for x86.
I'd be a bit careful saying that too loudly or too often

Just a 2 sec search and there was this one (from one year ago):
"we have taken a look at the PowerPC roadmap and there is plenty of life in it including 8 core designs under 30 W.
First off: Citation needed. Both for where this claim came from and the claim itself.
HyperionMP, aka Ben Hermans, not exactly a tech guy or known for his honesty.
You will not find any such chip currently on any manufacturers books. I doubt very much any such chip existed even on tape. The PA6T offered the theoretical option of tying (IIRC) 4 or 6, but no one has ever, or will ever produce such a chip. PA Semi currently only work on ARM for Apple.
But even if by some miracle Ben was actually telling the truth. An 8 core chip just means 7 cores of wasted wafer as far as OS4 goes.
One of the main benefits of Amiga OS 4.1 is the fact that the geared entirely towards the PowerPC architecture as one of the very few operating systems around. Linux runs fine on PPC but it certainly is not optimised for this architecture in any way."[/I]
OS4.x is coded in C. C is portable. And being geared entirely toward a dead end arch is in no way a benefit.
I'm not saying they hate x86. I am saying its not just that they are considering the effort to go x86 when sticking with PPC but also that they clearly still believe in PPC.
Some people believed Tony Blair and George Bush were smart, honest decent people too. Delusion is kinda cute like that.
