After looking further at the images, it appears that the maps are as follows
(note: Map 1 is oriented towards us, Maps 2-6 to people sitting on the left and 7-10 to the people on the right):
1: The Dothraki Sea, mainly deduced from the legend 'The Dothraki Sea' being visible
You can see the Forest of Qohor in the top-left corner. The blob near the bottom-right corner may be Qarth. Note the massive mountain range that now seems to form the eastern edge of the Dothraki Sea. This map doesn't appear to go as far north as Vaes Dothrak's location on the HBO maps, so VD's location has presumably been moved (either that or the Dothraki Sea map doesn't have Vaes Dothrak on it, which would appear to be pointless). Valyria is at the bottom-left but appears to be oddly squashed in shape, though the map is curling at that edge, so it may be an artefact of that.
2: The World Map. You can see Westeros at the top (the white bit at the top-right are the lands beyond the Wall). Sothoroys is the dark blob on the middle-left edge. Everything 'below' that is presumably the Jade Sea. The landmasses just above Sothroyos are presumably the Summer Isles. Right at the very bottom there appears to be a significant mountain range in the vicinity of what I would suspect are Asshai and the Shadow (maybe the Shadow Lands are simply called that because they are in the shadow of a large mountain range? That would be disappointingly mundane).
3: The Free Cities.
4: The Western World map, with Westeros, the Free Cities and the Summer Islands.
5: The Lands Beyond the Wall.
6: Unclear, but probably the Middle World map, featuring Slaver's Bay, the Dothraki Sea and Ibben (I'm pretty sure that's Ibben at the top of the map).
7: Unclear. The dark blob on the far right edge might
be Sothoryos again, so this might be the Eastern World map, featuring the Jade Sea and Asshai. Interesting if so, as it appears to show a previously unknown chain of islands or a larger landmass to the north to Essos, east of Ibben. Could this be the mysterious 'new continent' hinted at by Ran? Hmm.
8: King's Landing.
9: This appears to be another world map, but in a different style to the others, with fainter colours. Squinting a lot, it's possible that Valyria is still a solid landmass at this point on this map, so it's possible this is a historical map showing fallen kingdoms and empires. Alternately, this could be the character journeys map.
10: Fairly obviously, Slaver's Bay
Valyria looks like its proper proportions here from the book maps.
No sign of the Braavos map, unfortunately, but that should be in the package as well
