Phoenix Wright: Ace Attorney: Justice for All for the DS will be released Q1 2007, which is a remake of Gyakuten Saiban 2 for the GBA.
After skipping the GBA's part 3, Capcom moved on to Gyakuten Saiban 4 for the DS, which is an all-new game built from the ground up as a DS title. And looking at the below trailer it might have both Japanese & English language options in it like the original DS version did in Japan.
