Neither Fish nor Fowl
It's an interesting idea, but unless you really need x86 and ARM instructions in the same chip what is the point? It would be a very niche market and only of value in a Full Fat SoC with GPU and all I/O shared, maybe on a MS Surface Phone/Tablet able to run real Windows programs and Android Playstore Apps.
Performance, power consumption and cost is going to be poorer than simply a regular x86 SoC with an ARM core added or vice versa and much poorer than either a dedicated ARM or x86.
Perhaps Intel can find something useful in the IP. I doubt the staff will be employed long, though some may find suitable positions in Intel. Certainly I can't see the value of anyone other than Intel buying them. Not even AMD or the Chinese, it's too niche.
