Updated August 2, 2018: Following delays to the first three issues (see below), the just-solicited Punisher #4 has been pushed back three weeks as well. Punisher #4 is scheduled to be released November 27 - three weeks later than the October 31 date solicited one week ago.
Marvel did not specify the reason for the date change.
Original Story: Punisher #1 through #3 have been pushed back by Marvel, with Szymon Kundranski replacing the originally-solicited series artist Riccardo Burchielli. Announced in Marvel's weekly retailer newsletter, the publisher gave no reason for these changes.
Punisher #1 has been pushed back two weeks to August 22, with #2 back five weeks to September 26. Punisher #3, which Kudranski was already solicited to draw, has been delayed a full month, going from September 26 to October 24.
