Sony (SNE -2.6%) continues to slump following its PlayStation 4 event. The company's failure to reveal pricing info or actual hardware has drawn criticism, and some aren't impressed with the graphics improvements relative to the PS3. AMD (AMD -4.1%), later confirmed as the PS4's CPU/GPU supplier, is also lower, and so is GameStop (GME -1.7%) - though Sony promised not to block used games, the PS4's support for on-demand purchases via Gaikai might be weighing on shares. Activision (ATVI +0.4%) is outperforming a bit after announcing Diablo III will be released for the PS4. (previous)
