Yes.

In C++0x the object is default-initialized, which for a class type means the
default constructor is called. In this code, the default constructor is
deleted, so the code will not compile. See 12.1/5

Not quite: in C++0x the program doesn't call for default-initialization of
A::i, it calls for default-initialization of A, which is invalid because the
default constructor is deleted.
