The re issue knight's horse is called Destiny. There are three different versions available. Gold, Silver and Blue for each of the Knights. (Poor Cedric misses out!).

Destiny is light grey in colour with a white mane and tail. Unlike the original horses, there are no wheels in the hooves. Boxed Destiny's don't appear very often and I have seen them sell for more than original boxed Bravos and Valors. You can still get blue destiny armour, but even that is getting harder to come by.
