Looks nice, but as someone said, there's several adventure titles out or on the way for the DS which may or may not be translated.
Tantei Kibukawa Ryosuke Jiken Dan: The Masquerade Lullaby for example.

Also, for those of you who cannot find Phoenix Wright in the US, try Play-Asia.com. They have the japanese version (Gyakuten Saiban: Mask Vision Murder Case) for sale in the US and say it has options for both english and japanese language.
