Court Records forum user 'Tuesday' has generously translated a recent Famitsu interview with a trio of senior figures from the Gyakuten Kenji team, including Director Tsuyoshi Yamazaki, Character Designer Tatsurou Iwamoto, and Producer Motohide Eshiro.
Because Capcom seems to be hellbent on keeping much of Gyakuten Kenji shrouded in mystery for as long as possible, there's a fair few "we can't comment on that"-style remarks in the piece. That said, we do learn more about the timeline -- Eshiro reckons that the game is set "around Gyakuten Saiban 3 [Trials and Tribulations], I suppose," while Yamazaki observes that Edgeworth is "no longer the jerk in Gyakuten Saiban 1, but the one whose mind is changing, thanks to his battles with Wright." Elsewhere, there's a confirmation that "some popular characters" from the Gyakuten Saiban universe will have parts to play (but guess what: they can't say who).
Oh, and a surprisingly large portion of the article is dedicated to discussion about Edgeworth's running. In what is a first for the series, Gyakuten Kenji will have players directly controlling Edgeworth as he moves around various crime scenes, and it sounds as though the team really agonized over getting this new Edgeworth to look right. This even extends to the lawyer's running animations, which Eshiro describes as "graceful, while exerting effort." We're not sure Iwamoto is totally convinced yet, however, as he thinks Edgeworth looks like he's "walking really fast accidentally." Actually, that sums up our comical running styles pretty well.
