Since Vista will be DOA in a year's time you wouldn't expect that to be seeing any newer version of IE running on it at this late date while only the new sales of 7 will end not the support entirely. Until 12 is in beta however we still can't rule that out as seeing a 7 version available.

I would have serious doubts on IE13 simply being too new when that is eventually out as well as finding Bing search results listings for WMP 13 for 7? but only actually locating WMP 12 downloads available except for 13 at the MS downloads site for 8, 8.1.

IE 12 would seem to be the maker or breaker as far as 7 is concerned. Yet the open source community is still supporting XP and Vista as well as 7 there for the alternates. Regardless I am presently running with WaterFox 33 as the default browser which is where most of us will likely end being in order to keep 7 going if the newer stuff turns out to be 8-8.1-10 onlys.
