I've just heard from a friend at my local games store (who tends to be quite good for picking up on this sort of info) that Deathwatch may be delayed in Europe, due to FFG selling out of it at GenCon and redirecting the shipment to Europe to sell them in the US instead. This means that European gamers won't get the book until October, once it's been reprinted.
All this is laden with a hefty 'apparently', but if it's true, then I'm frankly disappointed with FFG... I would have thought they'd have expected this and accounted for it after the same thing happened with Rogue Trader last year.
So not sure which is correct or not.
