[ED: Since this question was asked the C++ Standard has been published. In my answer I have changed past tense to present tense and elaborated a bit on things that have clarified since release.]

The name of the language according to the Standard is C++. In order to distinguish it from other versions of the Standard it sometimes referred to as C++11, but that's not its official name. Previous releases are often referred to as C++03 or C++98, but in converstions on StackOverflow "C++" by itself generally means the current version of C++, whatever that happens to be.

C++0x was just a placeholder identifier used to refer to the pre-release version of the Standard before it was published in order to distinguish it from other versions. Today we have a new version being discussed by the committie; that version is currently being referred to as C++1y.

Regarding the 0x part, this is what Bjarne Stroustrup has to say:

The new standard is likely to be called C++11, but even a minor bureacratic delay could make that C++12. Personally, I prefer plain C++ and to use a year marker only when I need to distinguish it from previous versions of C++, such as ARM C++, C++98 and C++03. For now, I bow to convention and still use C++0x for the next version. Think of 'x' as hexadecimal.

When posting on SO, it is often referred to as C++11. There is some confusion about which version of the C++ Standard is referred to when only the C++ tag is used without any disambiguation (such as the C++11 or C++03 tags), but it is generally assumed that the C++ tag refers to the current release. As of this writing, that's C++11.

It has been approved! The official publication will take some time, but should still be out well before the end of the year. We can start calling it C++11 now.

Edit: Herb Sutter on 2011-10-10 announces that the new ISO standard has been published. The ISO Press Release has this to say:

ISO/IEC 14882:2011 defines the programming language and specifies requirements for implementation. Also known as C++11, this is the first major revision of the standard since 1998.

The last two standards were named C++98 and C++03, so one would assume this one will be "C++XX".replace("XX", YearAccepted).
