What about future Altivec support in both little and big endian modes?
For example, POWER8 supports AltiVec in big and little endian mode. I assume, if NXP is developing future PowerPC CPUs (QorIQ T5?), they will also support AltiVec in both modes, I hope.
Maybe one of the OpenPower members will develop a less power-hungry SoC or the IBM chips might become less power hungry when they move to smaller processes. Maybe we can see what A-EON and the Amiga guys have planned for future systems (of course, they are focusing on desktop PC's, so a more power hungry system isn't really an issue for them).
We only can hope. But I think the only company that is able to develop a stripped-down version that fits in an notebook are IBM itself.
Is someone aware what is Dan Dobberpuhl doing at the moment? Maybe we could hire him for developing a new PowerPC CPU

I don't think much about A-EON, because of the decision they made in the past. That is my personal opinion. I could be wrong, of course!
Imagine being able to develop a FOSS system around the Elbrus 2K architecture, that would turn some heads. 
VLIW? x86? Waste of money
Interesting CPU architectures for possible future projects are:
PowerPC (crystal clear

)
MIPS (very interesting!)
SPARC (maybe to power-hungry for notebook)
RISC-V
ARM (last place, because of the momentum they have already)
But first, we need this project working. Then the spotlight is on us and companies like IBM become aware of us.
On ownCloud, I wrote a doc with a lot of news sites, we should contact as soon as the crowdfunding is running to reach as much as people as possible.
