It's for games up until August, said Nintendo of Australia. Seeing how many hearts Link had in some of the trailer's scenes, I imagine they're pretty well along their way with it, so I can see it releasing by August.
OT: Not sure if the OP is serious or not, but the game overall really didn't look that great, which is typical of Dynasty Warriors games. Maybe they'll polish it up some by the time it releases, but I wouldn't expect to ever be able to call this game beautiful. I do like the scarf they gave Link though!
Yeah in one of the other directs they listed it as "Summer 2014", and I'd find that believable.
