Considering the 15" rMBP was released in mid-2012, I doubt you'll see it.
I have done every single solution found on the Internet and posted in forums to solve it but nothing has done so. The same macs work perfectly when in Bootcamp so clearly its a software issue.
Judging by the amount of similar posts I've found on here and Apple's support site, its clear ML does some funky **** to wifi. Therefore I was really hopeful when I saw they had released a wifi update and then left with sore nuts after seeing it was for 2012 macs only.
Apples support and attitude for older machines is starting to become very poor. Especially considering I paid over 4k at the time for my MacPro setup, and can't even get software with working wifi from Apple in 2012 :(
