I went into a Lifebytes(Apple reseller) store to compare the MBA and rMBP screen and weight differences. When difference in weight between the two seems almost imperceptible while there is nearly a half pound of difference. The screen differences are not as much as I would have thought but definitely the retina is great. 20 min in the store is just not enough time. No decision yet on which to get. The Apple refurb price is helping me lean towards the rMBP and I will not be waiting for Haswell.
