Blizzard released a lot of interesting tidbits today.[li]First off, the character limit has been finalized for retail.
Up to 10 characters on any one realm, and up to 50 characters total per account.
[/li][li]Next, we have several new details for the Collector's Edition.
Collector's Edition Pets
The special pets included with the Collector's Edition are the Panda Bear, Zergling, and Mini-Diablo.

Players who have purchased the Collector's Edition will be able to obtain their special pet by submitting the gift voucher found in their character's inventory to a special NPC located in each starting area. Players will then be able to choose from one of the three special pets.
Collector's Edition 10-Day Guest Pass
Players who will be accessing the game through the 10-day pass will create their account for that exactly the same way as a normal player, by visiting the account-creation webpage.
Those who wish to continue playing the game once the 10-day free period is over must first visit their local retailer or online store to purchase a copy of World of Warcraft. Once they have obtained a copy of the game, they can log in to WorldofWarcraft.com using their 10-day pass login information and then enter the authentication key that came with boxed copy into the field found at the bottom of their account page.
That's all that's required to activate a full-fledged World of Warcraft account once the 10-day free period has expired. Any characters that players have created during the 10-day trial, along with all their items, will be available for them to continue playing!
[/li][li]Finally, Blizzard is implementing Role-Playing servers with special rules. During the Open beta two Role-play servers will be open, Test 34 (PST) and Test 35 (EST).
