You could have just done a translation for all of us
Basically, and apart from the information we already know (new original series,
Mars kidnapping
Athena and all that),
Gō Wakabayashi just reiterates how they are going to use this story to show the role model that is
Seiya (holder of the
Sagittarius Gold Cloth) for the new generation of
Bronze Saints.
Kōga will have to fight also against (or maintain on their own) the reputation that the
Pegasus Cloth earned after the miracles done by
Seiya itself (that even surpassed the deities that are the
Gold Saints), and the notion that
Pegasus means
Seiya, a personal challenge for him.
To do that, they are keeping the same theme of sacrifice and friendship to make
Kōga & friends achieve that goal, confronting their enemies in battles where only their combined efforts can make them victorious, a story where without compromise and the utmost of the efforts there isn't a reward.
Mr. Wakabayashi says this is something not present enough as a theme on today's shows, and wants to achieve something like that again.
