BioWare (and Victory Games?) are clearly working on a military project that features tanks, APCs and what appears to be an isometric perspective. Rumours have linked them to the dormant Command & Conquer franchise... and if new domain registrations are to be believed, the new title may well be entitled Command & Conquer: Alliance. Fusible spotted fifteen domains that feature the game's title, which include EA in their registrant and contact fields. This certainly isn't a smoking gun - and could be a defensive measure - but it's very easy to add two and two together.
We'll know more at the VGAs later this month, when the title is set for a full reveal.
