To those complaining about all of the ladies...
When you think back on Zelda games historically, other than Link, the plurality of the characters that rise above 1 note NPC status have, in fact been female. Marin, Ruto, Saria, Navi, Zelda, Midna, Malon, Hilda, Impa, Din, Farore, Nayru, Ciella, Impa, Telma, the Great Faeries, Ilia, Tetra and even agitha had a substantial, rather important sidequest associated. Thinking of non-villain male equivalents you've got the king of red lions, mido, skull kid, the deku tree, the post man, Darunia.... and shopkeepers.
Now I missed a tonne, but at least my impression has always been that most of the significant NPC's have always been female in Zelda. Luckily as it is a dynasty warriors game the villain characters are likely to be playable,and there will be plenty of males as well.
Plus I doubt Aonuma was stunned by 9 characters haha, I think we're more likely to have triple that than end up with just the 9 playables. Also they seem to be announcing characters by games, I imagine all of the twilight princess characters are announced now, obviously we've moved on to skyward sword, and there are 3 DLC costume packs right? 1 is Skyward Sword we now know, one is twilight princess, do we know the 3rd? I would guess It's OOT/MM. I doubt we get any windwaker, phantom hourglass or spirit tracks characters due to visual consistency (as much as is possible in a musou game). I would expect announcements of Grouse, The bamboo island guy, confimations of playable Ghirahim, and demise, as well as perhaps a few few suprise residents of Skyloft, perhaps one of the patrolman riding on his loftwing. I imagine skull-kid, a good deal of the sages, and the happy mask salesman will be introduced in the OOT/MM block after they are done revealing skyward sword stuff.
