Yeah as I said in the other thread, I think this is a transitional hire. At age 65, he will probably retire in 5-8 years.
It buys Nintendo some time to properly vet and groom a true successor to Iwata though.
As for his track record, I guess the pro would be that he's lived in the US for a while and would hopefully have a more enlightened POV.
On the minus side though, much of NOA's decline occurred under his watch.
