Speculation of rMBP refresh

Good morning all;

With the recent rumors of a 12 inch retina Macbook air I began to wonder what the fall refresh of the rMBP would be like. Assuming that rumors about the 12 inch macbook are are true and the macbook air will use a fanless design and in all probability broadwell intel chips I am hoping that the 13 inch rMBP would become essentially a smaller 15 inch model (2880 x 1800, iris pro level gpu) but also closer to the weight of the macbook air at around 3.25 lbs. To me this would be the ultimate laptop, what do you guys think about the possibilities of this are?

Like I said I am just speculating on what I would like to see, but I don't think my wishes are too far out.
