D&O... correct.
100% JMO, but Wave will presumably answer the complaints & seek case consolidation & venue transfer of the NJ case/es into Mass.
after that, the first big test is class certification, which IMO seems likely to succeed. those who expect any dismissal solely on the pleadings are delusional IMO (Fed. R. Civ. Pro 12).
summary judgment is remotely possible IMO, but highly unlikely, as there are probably some notable disputed material facts at issue that would seem to preclude any disposition by any motion IMO. (Fed R. Civ Pro. 56).
IMO it'll get settled over course of the next six months to a year... but then again, i didn't attend a "Tier One" school, let alone #2 in the U.S.
