Sony PlayStation Vita's removable memory looks like it's an SD card, but it isn't

Sony's seen fit to tell us many of the PlayStation Vita's specs, how much it'll cost ($249 for WiFi, $299 for 3G), and who gets it (everyone). Amidst all the hullabaloo at E3 2011, however, we missed seeing that Sony was showing off the new handheld's internal memory cards. Good thing an eagle-eyed member of the public snapped a pic of the 4, 8, 16, and 32GB cards on the show floor. They look awfully similar to garden variety SD cards, only there's a little notch in the side confirming they hew to Sony's unfortunate habit of using proprietary storage formats. The cost of the cards remains shrouded in secrecy, but life's more fun when a little mystery's involved, right?
