Yum... I was glad to see this announced for an English release. Being the fan of the Phoenix Wright games that I am (though I have yet to play the Edgeworth spin-off...), it's hard not to be interested in what the creator of the series is doing next.
If anyone wants to give it a try, there's a Japanese demo available here. (Give it a minute to load -- the loading screen says 100% well before it finishes loading.) Even for the Japanese-illiterate, it's not that hard to figure out how to play through -- and it seems like an interesting game.
