Yesterday, the U.S. Supreme Court took action in one of the cases I've been following, Whirlpool Corp. v. Glazer, No. 12-322. The Court granted the cert. petition, vacated the Sixth Circuit's opinion and remanded the case back "for further consideration in light of Comcast Corp. v. Behrend, 569 U.S. ___ (2013)."
The docket indicates that both parties filed supplemental briefs last Thursday, March 28. I haven't seen those briefs, but my guess would be that they both addressed Comcast, which was handed down on March 27.
It will be interesting to see what the Sixth Circuit does with this case on remand. Its original opinion was In re Whirlpool Corp. Front-Loading Washer Products Liab. Litig., 678 F.3d 409 (6th Cir. 2012), discussed in this blog post.
