The interview with Dave Filoni wasn't the only source of The Clone Wars Season 5 details in Star Wars Insider #134. The magazine also revealed the titles of the first seven episodes of the season. Here they are:
"A War on Two Fronts"
"The Soft War"
"An Old Friend"
"The Rise of Clovis"
"Crisis at the Heart"

The Clone Wars Season 5 is set to premiere in September 2012.
