Speaking to Eurogamer, a Rockstar spokesperson said "it's looking like it'll be released after Table Tennis." As table tennis is expected on May 26, this means we are probably looking at a June or later release for the PlayStation 2 version of Liberty City Stories. It was previously thought that the game would arrive at the end of April, but this now appears incorrect.

Exactly how the PlayStation 2 version of Liberty City Stories will compare to the PSP original is unknown, but Rockstar has previously stated that it should go on sale for a lower than normal retail price.
