I would think the current iteration of the Lucasfilm Ltd. logo would be in there.

And Disney occasionally tweaks their logo for certain films, like Tron Legacy.

I know, I was just creating a worse case scenario really (Although it's a scenario that would be unsurprising). In all probability the Lucasfilm logo will be last before "A long time ag...".

The option I'd like best would be the fox fanfare played over the Disney castle logo (Unlikely but possible). It would have exactly the same feeling for me, as I don't consider the modern Fox logo to be SW either. But oldskool painted Fox, then oldskool Green Lucasfilm logo would be just a fantasy ;-)

But to be fair, if Disney make EpisodeVII better than the OT then from that point on I'll consider whatever combination of sound and visuals they used as the way SW should start lol.
