Take a pinch of salt with this, but you may be seeing the first piece of info as to when a beta test is coming for MAG.
Community Team member and Moderator of the English SCEE forums, Yaster, has been snapped playing the beta. Right now, this is most likely internal, but it shouldn't be before long until we hear something for the public.
Last year, Killzone 2, Resistance 2 and LittleBigPlanet had internal beta's before either being publicly released or trialed through SCEE's Beta Trial Member program.
Earlier in May, developer, Zipper Interactive, confirmed that there would be a public beta trial for the game before it's impending autumn release.
