It seems like fans of the recently-launched "Mortal Kombat X" fighting game still need to wait a little longer to see the title on older-gen platforms. 

According to reports, primarily from game observer and fan site Kotaku, sources within game retail giant GameStop has told customers checking the latest details on "Mortal Kombat X" for the Xbox 360 and PlayStation 3 that the title's release schedule has been pushed back. GameStop has also already updated its website to reflect the new release date for older-gen versions. The updated date now shows Dec. 31 instead of the original June 2 release. It is unclear if the Dec. 31 date for GameStop is just a generic date if the retailer has no specific launch period to note. 

The setback in the release of "Mortal Kombat X" for PlayStation 3 and Xbox 360 is already the second delay for the title. Originally, Warner Bros. announced the platform title to be released in April together with other versions. Earlier this year, however, the publisher announced that the PS3 and Xbox 360 versions will not be making it on the original release date, and the PlayStation 4 and Xbox One versions of "Mortal Kombat X" launched sans the older-gen titles. The publisher then announced the updated release date to be some time in summer. 

Many game sites, including Kotaku, have reached out to Warner Bros. for comment, but the publisher is keeping mum about the latest setback. Observers note that this is the second title for Warner Bros. with a delayed release on older-gen consoles and are wary of its implications. Another Warner Bros. title, "Shadows of Mordor," was also delayed for the PS3 and Xbox 360 and when the versions finally made it, fans were disappointed to see that the titles seem like a "stripped out" version of the current-gen game.
