You're right, sir!...
My prediction is that 2015 will be a "refreshing year" for both the 11" & 13"MBA as well as 13" & 15" rMBP. Both will be refreshed to Broadwell from Haswell (with the appropriate Broadwell chips...). Broadway & Haswell are pin to pin compatible, so that Apple can use the (almost) very same MB used in 2014 models. The only advantage to be gained by the consumer will be longer battery life due to the introduction of broad wells.
2016 (mid 2016 & onwards....) will be the real important re-designs year. I have my rather radical predictions there, when Apple will switch to Skylake. I even go as far as, deleting the 13" rMBP (bcz. I predict there will be a totally new design 14" rMBA, similar in aesthetics and features with the presently rumoured 12" rMBA...), and the rMBP line will consist of 15" & 17" models in totally new aesthetics and footprints (casings, etc.).
We'll see!...
