Leipzig is where SCEE like to show off their stuff, so we might see the "BBC game" there as that seems to be from one of SCEE's studios.
As mentioned, some things we already know are coming should get more detailed announcements; PS3 bundles, PlayTV dates for countries other than UK, maybe some more Platinum titles announced.
Seeing as it's looking unlikely PS3 will get a price drop this year it wouldn't surprise me if SCEE threw in a couple of titles from their new platinum range with the new 80Gb SKU.
