The North American PlayStation Store will be updated every Tuesday beginning May 4, Christina Lee--host of the PlayStation Network's bi-weekly video show PULSE--revealed in yesterday's episode. "We're moving to Tuesdays along with the PlayStation Store weekly update," she explained. "I'll see you right back here on Tuesday, May 4th."
Competitor Microsoft updates the online marketplace of its Xbox 360 console with new demos, add-ons and such sporadically throughout the week, though the release of download-only Xbox Live Arcade games are reserved for Wednesdays.
Nintendo, meanwhile, updates the Wii and Nintendo DSi's online marketplaces with games and downloads each Monday in North America and each Friday in Europe.
