NeoGAF user canIhasAnAccount discovered a temporary XBLA box art and banner for a new Strider game. Subsequently, users found a Strider entry on the Steam database, complete with icon of Strider Hiryu's face from the Capcom ninja series.
To extrapolate further, user Sega1991 found a Steam Community pageconnected by number with the leaked Steam information, posted by a user "ascarlston" whose profile offers a first name "Andrew." A quick search finds one Andrew Carlston in the game industry, a junior programmer at Double Helix. He's Steam friends with someone named Jorge Oseguera, a name belonging to a producer at Double Helix. Double Helix is the studio behindSilent Hill: Homecoming, as well as Front Mission Evolved and the Battleshipgame (based on the movie based on the game.)
As we find ourselves trapped deep within this rabbit hole, we called out to Capcom for verification of any of this. Capcom told Joystiq only that "We have made no announcements in regards to that title." In the absence of more info about that, why not look back at the last attempted Strider reboot, by GRIN Barcelona?
