I guess that's the downside when the native GUI for a platform is Qt itself.

I suppose we won't see some kind of Qt4Style, like there's a GtkStyle? 
KDE4 will be around for a while yet (even after KDE5 comes out), and 
this hinders adoption of Qt5 for people who consider KDE important.  I'd 
love to make use of some Qt5 features, but it's just not possible.  It's 
preferable to stick with Qt4 and have my apps looks good on KDE than 
going Qt5 and having the apps look like the odd man out.
