What's been keepin' ya, SanDisk? We knew these little buggers were legit late last week, but for whatever reason, the outfit chose to keep its trap shut until today. Finally, SanDisk has confessed in painful detail that its 16GB microSDHC and M2 cards are for real, marking the largest capacity available in both formats. Of note, even Sony doesn't have a 16GB M2 card on the market, though it's possible the firm is too busy dealing with all those other proprietary formats to mess with this one. At any rate, Best Buy Mobile and Verizon Wireless stores will be your go-to place for either one, though we'd be prepared to shell out $99.99 (16GB microSDHC) or $129.99 (16GB M2) when they land in November.
