It'll be because it's a rerelease. No ones gonna see a reissue of an album and be like "OMG! I MUST GET THIS ONLINE ASAP!" when they get their hands on it, unlike what would happen if they got their hands on a full album.
It probably hasn't even been dispatched to stores in Germany yet tbh. Or even if it has, it's the weekend, no ones gonna get their hands on it now until Monday.
On Monday/Tuesday it should start arriving in US/UK/German/etc stores so...
