To the 'prop=revisions', one can add 'rvparse=1' to get the parsed content of a page, however: http://en.wikipedia.org/w/api.php?action=query&revids=430490267&prop=revisions&rvprop=content|timestamp&rvparse=1 and http://en.wikipedia.org/w/api.php?action=query&revids=430489978&prop=revisions&rvprop=content|timestamp&rvparse=1 Give exactly the same content (note the different timestamps), probably the result of the last revid (see http://en.wikipedia.org/?diff=430490267&oldid=430489978 for the expected change).
Tested locally, and works for me on SVN trunk. I've got a feeling that fixing bug 28897 (earlier today) will have fixed this
