Are you confusing "Visual Studio 2015 ... uilding applications that run on platforms including Windows, Linux, iOS and Android." with "Visual Studio 2015 will run on"?
I was confusing "cross-platform" with "runs on", yeah. I thought that as Ars says Visual Studio is cross platform, that it would mean it runs on multiple platforms. A closer read indicates that may not be true.
