Center of gravity in the engine pod, definitely. Just because the cockpit is the only place that swivels, doesn't mean it's the center of gravity, even though it seemed like it was in the games. We have the technology (I assume) to put the viewpoit somewhere besides the center of gravity.
I'm not quite sure what you mean by that. If the whole fuselage rotates arount the cockpit, then the centre of mass would be in the cockpit. The eyepoint hasn't got much to do with it where it's rotating.
I've thrown a little simulation of a b-wing. It's not much compared to brand's b-wing, but it illustrates the idea of having the centre of mass in the cockpit and how it affects gameplay. It looks a little bit odd flying around, but not too bad. There's no mission supplied, so you'll have to make your own.
p.s. If I said centre of gravity before, I meant centre of mass. Maybe a pointless distinction, but whatever.
