There are many more reasons why NX wont use zen:
Why would AMD put their top of the line new cpu in a low margin console business, the first thing they will use it for is servers which are high margin.
Second, they probably cound'nt make enough of them for this holiday season.
Third, it would make the NX much more expensive which is counter to Nintendo's philosophy.
It may still be x86, just not zen, like a beefed up carizzo or something.
