A word of caution before everyone gets too excited:
For the court to ask for oral arguments on Motion to Dismiss is highly unusual but we can't assume the judge is on the verge of dismissing the case. He apparently has some questions he wants the attorneys to answer. We don't know what those questions are. We should not expect an instant ruling "from the bench." At the end of the hearing the judge will probably take the answers "under advisement" and issue a written ruling on the Motion within a week or two. He might throw out some parts of the complaint and leave others standing. Or he could dismiss the case, point out the errors, and give the plaintiff an opportunity to re-submit. Or he could dismiss the case "with prejudice" which would kill it at least within his jurisdiction - that rarely happens.
That said, hearing the nature of the judges questions should tell us something about how he views the case.
