Sony has told Eurogamer that "last minute technical difficulties" are to blame for the absence of yesterday's expected PlayStation Store update.
Gran Turismo 5 Prologue was supposed to go on sale, alongside a demo of UEFA Euro 2008 according to EA, and the new Grand Theft Auto IV trailer.
"Unfortunately due to some last minute technical difficulties, we were unable to publish the new content to the PS Store yesterday," Sony told us just now.
"We are working to resolve these issues and will let you know as soon as new content is posted."
The platform holder has not said whether or not we will see the update today or later. So fans of GT might want to go outside in the rain and buy the Blu-ray version instead.
