It is on the compiler team's "shopping list" but personally I hope they don't waste time and money on it.
I and many others have been using IBM's free CGIDEV2 for many years - I wrote about it here:
http://www.ibmsystemsmag.com/i5/enewsletterexclusive/13613p1.aspx and others have wrtten articles which Google should be able to find for you. A couple relate to using CGIDEV2 to produce Excel spreadsheets, but the principal is the same.
As Joe noted the COBOL XML generation is very limited and almost invariably requires a transform of the document produced for it to be usable.
I'd rather the compiler folks spend money on things that we can't do for ourselves.
