The PDF's you have seen in the past were not for public release, the culprits were dealt with quite severely i believe. Thats not to say images won't leak again in the future, but the current period is always an extremely difficult one for retailers. We know what is coming and are in the process of ordering it if we haven't ordered it already, but the brand have not officially launched. I would not expect them to do so until after the Lords trade show which is in early September.
Most retailers have catalogues, and whilst i'm sure its not officially allowed, there isn't much harm in allowing customers to have a quick flick through. I wouldn't let anyone leave with a catalogue or take pictures on their phone though.
