Update 7 is bringing much more in addition to the two new races. There will be a 12-man raid at level 6, the first large raid suitable for players below level 10. It will be added to the Devil Assault Adventure Pack, so if you already own that one, you'll find it within that arc. Devil Assault will also gain epic mode with this update. The raid isn't the end of new content, of course. There's a new adventure pack coming, and this one's free! This level 12 quest arc will send you to solve the long-running mystery of Nat Gann's fate, and it may or may not involve time travel.
There are some updates coming to the UI and basic game that players will definitely enjoy. You'll find a slight change to the UI color, but that's not the best part. The inventory UI has an upgrade that will allow you to sort your items by type, making it much easier to keep things organized. You'll find tabs for each gear type, ingredients, potions, and more. And finally, the auction house got an update that should have DDO fans jumping for joy: search. That's right, Update 7 will bring string search to the auction house. You'll be able to search across categories, choose exact phrases, or be a little more general.
Engine upgrades to enable DX11 graphics, reactive water, hireling AI upgrades, bug fixes, and a few more special surprises round out this exciting update. Want to know more? Keep your eye on Massively -- we'll be taking an in-depth tour of Update 7 later this month!
[Update: To clarify, both of the new races will be available for purchase in the DDO Store.]
