There's an interesting rumor going around right now on many of the Vanguard fansites that Sony Online Entertainment plans to buy Vanguard from Sigil.
The thread where the rumor originated can be found over on VGFlames, but it's spreading like wildfire, and there are now threads about it over on Silky Venom, and Fires of Heaven, among others.
It's important to note that right now this is very baseless; it may or may not happen, but until something official is announced, it's nothing more than "he-said-she-said," and that should very much be taken into account when discussing it.
