I caught a whiff of this info last week, and then it was on The Register web site yesterday. Looks like the parent company of WROX is gone, which means WROX is gone too. Nothing mentioned on ASPToday yet (luckily my subscription just expired this month), but then again that site was so poor that I wouldn't expect to see anything until after they are gone. :|

Kind of a sad day, I have mixed feelings about them going under...
