perhaps they will get renamed, as they did with the moulding board (became floured bread board on release in SA)
I've never had one of the old Ilshenar maps, but I was thinking... was surprised the other nite to click one of our treasure maps and see the new version of the map, I had thought that they would all stay in the old style until the whole thing went live to shards, and that's what got me thinking... wouldn't it be nice for the old Ilshenar maps if they kept the old map line-drawing style on them? seems to me there could be an easy way to identify them right now, before release
then again, maybe not.... one of our old maps *became* an Ilshenar t-map, and you know there's no way we grabbed one of those as loot last year
