Does InstallShield 2013 Premier integrate with Visual Studio 2013?

Currently we use Visual Studio 2012, which allows me to include an InstallShield 2012 Spring or InstallShield 2013 project as part of the VS2012 *.sln file. We are thinking strongly of migrating to Visual Studio 2013. I have installed VS2013 and IS2012 Spring w/SP1 as well as IS2013 Premier onto a test computer. But I cannot get VS2013 to "see" the *.ism project files when I try to include them as part of the VS2013 *.sln solution.

So I am wondering if we need to wait for the next version of InstallShield (to be named InstallShield 2014, I assume ;)) before we can move on to Visual Studio 2013.

Anyone know for sure?
