Still wondering which version of Daffy we're gonna get if the leaks are true. Marvin is based off the HBO Looney Tunes cartoons, Taz is based off the 90's design/TazMania, and Bugs seems to be a a mix that takes mostly from the LTC design but with a different, more typical palette and some altered features here and there.
I've seen animations of Daffy on Youtube/Twitter that I think are fan made (they're damn near official looking), and it's the Chuck Jones design, but with moves referencing multiple incarnations of the character, which would be perfect. The LTC version is fun but they should really go for a definitive composite character.
