According to this Examiner piece, Square’s announced an Extreme Edges label to categorize its western games.
The first three Extreme Edges titles to be released in Japan are Raven’s Singularity, IO’s Kane & Lynch 2: Dog Days and Blur Racerz (Bizarre’s Blur to you and me).
Blur and Singularity are both Activision titles in the US and Europe.
There’s no detail there on whether or not games are going to be branded Extreme Edges in the west. We’ll ask.
