I want to know the answer to the following question:
When did the company release a trailer of the horseback riding aspect?
All the background I'm provided with is that "The game was scheduled to be released the next year, and was no longer a follow-up to The Wind Waker; a true sequel to it was released for the Nintendo DS in 2007, in the form of Phantom Hourglass.". Is that enough to answer the question?
