In hindsight, if Nintendo could do it over again, they almost certainly would not use PowerPC for the Wii U, but it's obviously way too late to change it now.
They thought that having backwards compatibility with the Wii would help them a lot more than it has and that Wii U would sell a lot more, so they would eventually be able to scale down the cost of it even if it's a more rare type of processor these days.
In hindsight though Nintendo would probably do a lot of things differently though, they'd probably ditch the Wii brand entirely and never have gone near the tablet controller idea.
