What is the fate of wchar_t in c++0x?

What is the fate of wchar_t in c++0x considering the new character types char8_t, char16_t, and char32_t?

More importantly, what about std::wstring, std::wcout, etc?

Are the w* family classes deprecated?
Are there new std::ustring and std::Ustring classes for new character types?

Nothing happens to wchar_t, it is still implementation specific (and compatible with C).

The new types char16_t and char32_t have defined semantics in the new standard. The old wchar_t might be equivalent to one of those, but likely to a different one on different implementations. Or none of them, on some systems.

You will have typedefs u16string and u32string for strings of the new character types, but no new standard streams.
