It's confirmed on official Capcom X account that the wolf on the teaser is in fact Amaterasu and that we will play her, not an adult version of chibiterasu, so yay sorry for Okamiden fans but it seems the game is being removed from canon.
The change of protagonist was the least of that game's problems honestly. It could have been a good game with a totally different character.
Really it was supposed to be a sequel but it played like a bad commentary track on the first game.
The kid characters (more like bad clones) were uninteresting, they went to the exact same places, to meet the exact same people that weren't doing anything but reminisce Okami's events.
The very few new elements were so boring. New enemies were a brownish generic mess, made even more obvious during the time travel bit where we get to fight enemies with the old, vastly more creative designs.
And of course on the purely technical aspect, they fucked up by trying to replicate exactly the environments of the original on a DS, because the way they did it was hacking them into extremely tiny spaces with long loading times between them, ruining the pace. They should have made a game adapted to the DS to begin with, even if it meant scaling down some things.
There's no equivalent to the Nintendo DS these days, no excuse to make something that awful now.
I feel like Okamiden could've been a better game had they released it for the PSP instead of the Nintendo DS. They could've used bigger maps, better graphics, and still had somewhat decent controls.
I don't think the DS is an excuse for how bad it was. It certainly doesn't explain how pointless and lazy the plot was.
Sure it was made worse by the terrible way they split the map, but that's their fault for trying to replicate the exact areas from Okami instead of trying to make a new game adapted to the hardware they had.
This is exciting news, Okami is one of my favorite games and it would be very nice to see a sequel for it. I hope they keep a similar if not the same artstyle as the original one. Either way though it'll be really nice to have a sequel since as most people know, original left on a bit of a cliffhanger.
