The original Xbox One used a Jaguar[0] based chip, which is really quite a different bread than the Bulldozer or Zen micro architectures. (It's closer to what you'd find in a netbook than in a high end machine, minus the custom memory cache/controller setup AMD designed for Microsoft.) While it's possible they'd switch micro-architectures, if history is any indication, I suspect it's more likely what you'll see is a die-shrink (28nm -> 14nm) combined with higher clock speeds. And hopefully a faster memory controller (I think that's more the bottleneck than raw CPU power). But that's entirely my speculation.
