When one can run Visual Studio on OSX/Linux...
I suspect we'll see a new 100% managed code IDE in the next 3-5 years that will fit this area nicely. It'll have bits of Visual Studio in it and it may even be called Visual Studio but it won't be what we have now.
--As people pointed out, this isn't true. I was confused by Ars Technica's headline declaring VS to be "cross platform".

AFAIK only .net will which is not visual studio.
