Konami Digital Entertainment has announced that due to the stay-at-home order imposed to slow the spread of the coronavirus in Texas, operations of one of its product manufacturers have been “temporarily impacted,” affecting release dates.  Eternity Code Boosters, originally scheduled to street May 1 (see “’Eternity Code’ Brings Plunder Patroll to ‘Yu-Gi-Oh! TCG’”) has been delayed and are now expected to ship in early June, the company said. 

Just a week ago, Konami told us that its releases, including Eternity Code, were proceeding as scheduled (see “’Yu-Gi-Oh! TCG’ Releases Continue as Scheduled”). It appears that Secret Slayers Boosters, scheduled for April 3, and Structure Deck: Mechanized Madness, scheduled for April 17, were shipped prior to the printer shutdown.
