Ah, Maelstrom (UK) have the same release date.
I've had WFRP stuff on pre-order from Maelstrom before, and I've found that when its released earlier than expected, their release dates don't always get updated. When I've spoken to the shop, they have said they rely on the main distributor for release dates, and don't always get told if these change, although that could well be down to Maelstrom rather than the distributor.
Anyway I think the UK distributor (Esdevium) is also responsible for Europe, so it may be Fantasiapelit simply haven't got an updated release date?
Could be worth checking with them if you haven't already, to ensure they know the game has been released already. I've done that with Maelstrom a couple of times in the past and then they managed to get hold of my pre-order from the distributor, and ship it a few days later, and updating their release date at the same time.
