It reminds me 'Worse is Better'  
(http://en.wikipedia.org/wiki/Worse_is_Better).

I'm not a C++ expert but I haven't any serious problem with C++. And such  
features allow me to write in C++ more productive and use all my codebase.  
So I'm affraid many expirienced C++ programmers remain with C++.

Because of that D must be focused to different programmer audience, to  
compete with Java/C#/Scala...

Yes, but now there are only few C++ compiler vendors (unlike 98). There is  
hope that GCC will have almost all new C++ features in near future.
