Gamertell has posted impressions of Ace Attorney Investigations: Miles Edgeworth based on a hands-on demo available at the 2009 San Diego Comic Con.
From the article:
"The game still has the quirky feel, and the characters are a funny as ever. Capcom is hoping for a February 2010 release on the DS. It has been released in Japan for some time now where it is already a huge hit."
