I found it funny (derogatory) that the 456 announcement trailer, when showing off all of the major characters in each of the games, showed Edgeworth in DD. that guy barely even does anything there. but it's obvious they put him in because Edgeworth's one of their most popular characters and showing him off in the trailer is more likely to interest trilogy fans.

now, if only there was some way they could promote Edgeworth in a larger role. say, if he was the protagonist of some other ace attorney games. which they could port to all modern platforms. I bet that would interest a lot of people. if only it was possible.
