With Samsung using CloverTrail+ in Galaxy Tab 3 10", it strongly signals they are interested in using Bay Trail and Merrifield. I agree with AE...I would not be surprised to see Merrifield inside Galaxy S5 and the Note 4, and Bay Trail in Samsung's premium tablets.
As for Apple, I used to think there's a possibility of a fab deal between the two, but after seeing info on Silvermont, i'm throwing that idea in the garbage. Silvermont has such a performance/power advantage that Intel would be crazy to do any fab deal. I'm thinking that Apple, like Samsung, will replace or create another line of products based on Bay Trail and Merrifield.
