I agree with that open licensing. It could have helped Power architecture as a whole back then.
As for Apple and Macs, moving to x86 was a step that made software ports much easier. Not so important for some of the big software companies, but for the smaller ones. And i really think that the software side helped Apple.
Again, that is one of the most important points with x86 CPU's in PS4 and One. It's not the ultimate CPU architecture but it makes live easier for developers. Especially the smaller ones.
Making live easier for devs has become a key element over the last decade, while both architectures can give developers enough power for everything.
Back to Wii U, as i already said i would have loved to see a 1.6GHz quadcore PPC. That should have been powerful enough at least for every last gen port, or even graphically improved ports.
Nintendo going x86 would have been fine for me as well though it would have cost them Wii compatiblity.
