In one of the other threads Matthew Sprange said that the 2nd printing would be released at GenCon, which is in August I believe.
Since that release signals the end of the SoC program, I'd guess that the catch up period would be late July or early August. IIRC one of the mongoose people (mongooses. mongoosi, mongeese?) said it would last for several days.
Keep in mind that that is only a guess on my part. For what it's worth.
