Today Joystiq posted an in-depth preview of L.A. Noire that describes the demo of the game that a Rockstar representative showed them. Here's the final paragraph:
"LA Noire is, as my colleague Andrew Yoon put it, a "big-budget, M-rated Phoenix Wright." It's a police simulation of the highest caliber and, for a person who may be out of love with the Rockstar formula, Team Bondi's LA Noire offers the prospect of an open-world game for those of us who don't want to play the antihero."

This is a day 1 buy for me, so I just quickly skimmed the article to not spoil anything for myself.
