Even though Hyrule Warriors is only a week away from release, we already have an amazing DLC lineup into February of next year. First off, we have Cia, Volga, and Wizzro joining the disc based roster in another update. We'll be able to use them on the day we pic up our copies. As for the rest of the DLC, we'll be purchasing them for a nice price. The first DLC, dubbed "Hyrule Warriors Master Quest" comes out in October 16th and adds 2 new costumes, a new Adventure map, a new weapon, and a new scenario. Then we have a Twilight Princess Pack and a Majora's Mask Pack, both of which include not only new costumes, but new characters altogether. Then there's a Ganon Pack that includes two new game modes.

Finally, you can pre-order all them together at the likely price of $15 and get a Dark Link costume as an added bonus. 

Now, everything at the link provided will list the price in Yen, but Nintendo of Europe tweeted the Dark Link skin, so my bet is these packs will be purchasable from the eShop on Day 1 of the English Hyrule Warriors release.

I'm glad they are adding a Majora's Mask Map,hopefully we'll get a Wind Waker and A Link Between Worlds/A Link to the Past Maps someday.I'll preorder the full package,15$ for all that extra content is reasonable.
