I would absolutely ADORE a Klavier and Ema game and take one of those over another Edgeworth game everyday of the week.
(And, I'd actually love a Franziska game, but she's my favorite character in the series so I'm a bit biased XD)

TBH, I didn't really enjoy AAI's gameplay and plot that much (though i didn't finish playing through it so MAYBE IT GETS BETTER?) and I don't want a sequel.

Oh Capcom, why ;__;
