German court ruling bans using "coming soon" for release dates in regards to pre-orders
Due to a recent German court case, in which the European retailer MediaMarkt was taken to Munich Regional High Court because of excessive delays on a pre-ordered product, a new law has now been put in place. If a game or product is available to pre-order, it MUST have a specified date of when it will ship and arrive, and it must stick to that. If a delay occurs, then the consumer is allowed a full refund. Listings that say "coming soon" "tbd" or "unspecified" are fine, so long as they don't take money from the consumer.
