Like I said, don't overestimate the value of "one more" IDE, which is what VS11 is. There are plenty of good IDEs, including previous versions of VS, which people can use already. These IDEs have Intellisense.
There are plenty of great compilers and toolchains out there too. If you don't like the Visual Studio IDE and you don't like the Visual Studio toolchain (because it won't compile for XP), why are you bothering to use Visual Studio?
