I think the most interesting thing we'll hear is Sony's response to the whole M$ DRM fiasco.
They have an extreme play they can make that would make them VERY popular with gamers, but very unfriendly to publishers. Will they make it?
I personally think they could make a "digital copies are $10 cheaper than physical, but physical copies won't require DRM or an internet connect" and they'd come out smelling like a rose. If they don't come up with an enticing counter-argument to M$'s "always online" approach, that also addresses the publisher's need to counteract the used market, all hell is gonna break loose on the internet tubes.
