As this is the first we've heard about any sort of PlayStation 3 hardware shortages, we followed up with Seybold to make sure he wasn't only warning about future supply issues, but also explaining January's sales of the console. He told us: "Yes. The strong demand carrying through the holidays was evident and early in the month we [knew] there was going to be limited supply of the PS3 at retail in January. We're working closely with the retail channel to meet this demand, but expect tight supply for the coming months."
The upcoming supply issues may also be a result of Sony's "upcoming line up of the industry's most anticipated games" -- games like Heavy Rain, God of War 3, and ModNation Racers. Seybold additionally points out that "this momentum is fueled by a stellar holiday" and the recent releases of games like MAG and BioShock 2. We here at Joystiq have yet to see the shortages at our local brick-and-mortars, but feel free to let us know if you do!
