Sony has been on a trademarking rave it seems, the firm has trademarked two new titles, Guns Up! and Everything's Game.
The trademark for Guns Up! mentions "Computer game software; Downloadable computer game software via a global computer network and wireless devices; Video game software," so we know it's a game, not an online game or service.
The Everything's Game trademark however is filed by Sony Online Entertainment, the firm's MMO publishing arm behind Everquest and Planetside 2. The listing mentions "Entertainment services, namely, providing online multiplayer computer games for others via the Internet," so it has something to do with an online game or service.
You can add this to the recent list of trademarks filed by Sony, last month the firm filed for Kill Strain and Entwined trademarks. We're guessing some of these are to be revealed at E3.
