Well, it was only a matter of time before this happened. The game does belong to SoE, after all, so it only makes sense to have the developers all in one central location with other SoE teams for collaborative and communication reasons.
That said, it also appears that Dave "Hasium" Gilbertson is no longer the game's Producer; Thom Terrazas - previously the Producer of PlanetSide - has taken over the reigns.
The Vanguard development team is relocating its offices to SOE's San Diego campus effective Monday, October 15, 2007. As part of the integration into the SOE family, the developers will benefit from having access to shared resources and the combined experience of SOE's other game development teams. As a result, not every Carlsbad employee has been invited to stay with the development team.
Under the new leadership of Thom Terrazas, an eight-year SOE veteran, SOE will continue its commitment to Vanguard and its players. The remaining Vanguard team members are going to continue to deliver on an exceptional product. They are a creative force in the online games space and we look forward to continuing the vision for Vanguard and to continue to deliver groundbreaking game play. SOE remains committed to seeing Vanguard grow and prosper.
