Sony Computer Entertainment America appears to be working on a game called TV Superstars.
The trademark they registered (below) is for use with games and “operating a real-time game for others over global and local computer networks.”
To quote: "Looks like SCEA may be working on a brand new multiplayer online game called TV Superstars, as evidenced by a new trademark unearthed by Siliconera.
Details are scant beyond the fact that it's both online and a game. Our first guess? It's Sony's attempt at competing against Xbox LIVE's 1 Vs. 100 application (pictured above). With so little information to work with, we can't really offer any other hypotheses."
