Yes the article was published. Here are all the references I have found to
Oberon in the literature:
 N. Wirth, "The Programming Language Oberon". Software Practice and Experience,
 Vol 18(7), July 1988, 671-690.
 N. Wirth, "From Modula-2 to Oberon". Software Practice and Experience,
 Vol 18(7), July 1988.
 N. Wirth, "Type Extensions". ACM Transactions on Programming Languages and
 Systems, Vol 10(2), April 1988, 204-214.
 H. Mossenbock, J. Templ, "Object Oberon - A Modest Object-Oriented Language",
 Structured Programming, Vol 10(4), November 1989 (to appear).
 N. Wirth, J. Gutknecht, "The Oberon System". Computer Science Report 88,
 ETH Zurich, 1988.
 C. Lins, "Programming Without Enumerations in Oberon", Structured Programming,
 (to appear).

Yes, a 4th edition exists. There are a few changes to Wirth's language
definition mostly involving reducing the importance of the type CARDINAL. The
type still exists, but the book uses INTEGERs instead. The book has been
re-typeset in a different font, leading to what I think is a much more readable
manuscript. I know that the module RealInOut has a new routine called (I think)
WriteRealFix which lets you write a real number in fixed (decimal) format.
