Sony has announced that the PSN store “should” be up and running by the end of the week. Since April 20th the Playstation store has been “Under Maintenance” which means nobody can download any kind of DLC or redeem any codes. Rumors were flying around the net last week that the Store was coming back online on May 24th, only it turned out to be to be exactly that, a rumor. If by the grace of the Gaming Gods the store does return you can expect a full update, only I wouldn’t hold my breath until then. But I will keep my fingers crossed.
