The tweets I saw said that "when the time was right" was WotC's response to when they would do a new print run of the PHB. Apparently they haven't decided whether they will print a corrected version (errata changed) or just do another print-run of the original book. I imagine which will depend on how far along they are with this edition, how soon or if they plan to switch editions, and whether they think enough people will buy it to justify the expense of new formatting that would be required.
