I had started some time ago a translator/preprocessor project that
parses Obj-C 2.0 statements and is intended to expand them into Obj-C
1.0 and standard C extensions. E.g. expand the new enumerator loop to
some implicit while((x=[e nextObject])). The status is that I did not
have enough information about the final syntax of ObjC-2.0 from
official sources and had to stopp work.

Now, as Xcode 3.0 is out the needed information is probably also
available. Maybe, this translator project can help as well.

Link to the sources if someone wants to take a look:
