What future? Intel have been powering PCs for decades. They know better than Apple in this field. Heck, even AMD probably knows better.
If Intel knows what they are doing, then why is Qualcomm killing them in the mobile space? Why was Broadwell delayed for so long? I don't think Intel is as steady as you think. Anyone that understands Apple knows that they would drop their reliance on a 3rd party as soon as possible, including Intel. You do realize that Intel is the only reason new MacBook Pros and iMacs haven't been released already? Apple HATES that. They will shift to ARM as soon as it will be accepted in the market.
