There is never going to be a Dragon-Ball z legacy of Goku 3 but there is Dragon-Ball Z Buu's Fury which is basically what happens after Dragon-Ball z legacy of Goku 2.
According to Dragon Ball Wiki, yes, there is one, but it is called Dragon Ball Z: Buu's Fury. It is still the third part in the trilogy, even though it doesn't have the "Legacy of Goku" title. Source: Dragon Ball Wiki
