The xps 13 this year seems to have the same wireless chip on both windows and developer editions. They both seem to have the same killer wireless chip.
It is good to note though that not all "same laptop but different OS" are actually the same laptop. Be wary and check hardware before buying the windows version to put linux on... it wont always work. (In this case obviously, the wireless is at least a non issue)
