Will the Ninth Circuit affirm nationwide certification of state law claims?

In the matter of Mazza, et al v. American Honda Motor Company, the Ninth Circuit will hear oral argument on June 9, 2010, at 9:30 a.m., in Pasadena, California.  Defendant's Rule 23 Petition was granted after the District Court certified UCL and CLRA claims on a nationwide basis.  The District Court's extensive discussion of choice-of-law analysis may be the primary focus.  The outcome may prove to be significant for the many Toyota acceleration cases assigned to Judge Selna in the same Central District from which Mazza was issued.  I would like to attend and provide a detailed account of the argument, but my schedule may not permit it.  If I cannot attend, I will try to arrange for someone to report in my absence.
