Edgeworth's memory of case 4 is flawed from the blow to the head he took at the start of case 3Hence the sketchy tech level (flat screen tv+video tape).
Case 3 of AAI2 will lead directly into DL-6More specifically, once the case goes to trial, Manfred von Karma will receive his first penalty and take his revenge on Gregory Edgeworth. We already know that the third case will feature both Gregory and von Karma, so when coupled with the precedent the first AAI set for copious amounts of Continuity Porn, it seems natural that the writers would want to tie it in to a pre-established event in the series. What other event is there besides DL-6?
Franziska von Karma will be the one to investigate and capture Shelly de Killer.noteMore like wishful thinking; one of the games in the AAI series will involve switching to her perspective to track him down because It's Personal (In 2-4, he shot her).
AAI 3 will feature Phoenix and the Gavin brothers and the events surrounding his disbarment.When you look at the dates, AAI 2 ends only a week before Magnifi Gramarye's death and Zak's arrest. And consider the relatively small timeframe for the two games (less than four weeks between Turnabout Airlines and The Grand Turnabout).
What the names might be if AAI 2 gets localized
In "Turnabout New Year" in the manga, Gabriel's death was also murderTheir causes of death were the same, and considering that the killer seemed to want to set up there being a "curse" so that Tucker would get scared and abdicate the presidency, it stands to reason that Gabriel would be a natural start. As for why no one else figured this out, there are several cases in which past murders went unsolved until Phoenix or Edgeworth took the case (see DL-6, SL-9 and IS-7)
Desirée DeLite is the daughter of Bansai Ichiyanagi
Franziska was in America with her father when the DL-6 happened.Bansai Ichiyanagi notes that Franziska used to call him Oji-chama (in the fan translation, Unco Boo Boo), which means she was very young at the time Ichiyanagi is referring to (and at the time of the DL-6, she was two). Since Edgeworth doesn't recognise Ichiyanagi, it couldn't be after the DL-6. Of course, the problem wit this theory is that Franziska is never brought up as being in the courthouse at the time, but since her father was in court, and he and Ichiyanagi were friends, Manfred may have left his daughter in Ichiyanagi's care during the trial, and Franziska doesn't have many if any memories of this because she was, well, two.
The Mastermind AKA Simon Keyesis the Phantom.
Justine Courtney is a time/universe displaced member of the Adeptus ArbitesIt fits in with her more-than-borderline-religious view of the law; in her home universe, worshiping the Law as a manifestation of God(-Emperor) probably isn't even that much of of a notable quirk (believing that the Emperor is in fact an Emperess probably is, but nothing heretical given the gender-blind nature of the Imperium). After getting over culture shock, she decided to make herself a permanent resident on the basis of how not-hellish the Ace Attorney universe is compared to her home, although she's ideologically stuck in dogmatic and merciless application of the law.
