But what we need first and foremost is a reliable, native MinGW environment for developing Qt applications, since the vast majority of Qt developers that develop for Windows also develop _on_ Windows. Now one can argue that Qt itself could still be compiled using a cross-compiler. But if we're not able to compile Qt ourselves with the native toolchain, how can we be sure other complex apps will work?

This is more a long term goal because atm no common way of cross compiling a custom mingw version is available (only 
scripts "here and there").

Depends on the release date of Qt5, if it happens in 3 months I think it is possible.
But Qt5 should not be delayed only because of MinGW, most Windows developers don't care about mingw.
