Newsbrief: Social games giant PopCap today announced that it will launch the next game in its Blitz franchise, Solitaire Blitz, in March via Facebook. The game, which follows on from other big hits Bejeweled Blitz and Zuma Blitz, is set underwater and promises an "un-solitary version" of the classic card game. PopCap plans to roll the game out gradually over the coming weeks via a staggered beta launch, before then making the game available to all Facebook users by early March.
