WizKids has pushed back official release dates on imminent releases in the Marvel Dice Masters and D&D: Attack Wing lines due to port delays.  Earlier this year, shipping companies sold their chassis (the wheels that go on shipping containers so they can be moved by truck) to leasing companies, who are not as adept at having the chassis in the right place at the right time, according to JOC.com.  This has caused congestion at the Los Angeles-Long Beach port that is affecting a wide variety of shipments.    
Though stock on the two delayed WizKids products has arrived at other distribution points around the country, and in some cases has even shipped to stores, delays in supplying the west and southwest warehouses from the port has caused the national release dates to be adjusted.
Marvel Dice Masters: The Uncanny X-Men, which was scheduled to release today (October 22) has been delayed till October 29th.  Stores who have already received this product are required to hold it until the new release date.  Dice Masters has been plagued by supply chain problems since launch, and WizKids has been playing catch-up with demand (see "'Marvel Dice Masters' OP and Restock").
D&D: Attack Wing’s (see "Details and Pics for First 'Attack Wing D&D'") adjusted release date is also October 29th, but Diamond customers may only receive the Starter, Wave One: Green Dragon Expansion Pack and Wave One: Hobgoblin Troop Expansion Pack; with other Wave One expansions following a week later.  North and South American release dates outside the U.S. will also be delayed, with release planned for November 5th.  The first monthly Storyline OP Kit (see "'D&D: Attack Wing' Storyline Organized Play"), will also be delayed a week, now planned for release on November 12th.
