There won't be any GTA-esque lack of consequences for committing crimes.
Where did you see it? The protagonist escaped into a parking garage and the cops gave up the chase. Seems GTA-esque to me except for the car repair and respray
Read the proceeding sentence to that quote, and watch
this video (Old link got deleted - This one has commentary, though).
In the video, there's a part where the protagonist pops up on the TV behind a store owner. The store owner glances over his shoulder at the TV, then slyly reaches over and presses an alarm button while the player is distracted by all the cool guns and stuff. This in the middle of a video that's supposedly about free roaming - So while the player might be able to circumvent this somehow (Unconfirmed, but likely), it looks like you won't be able to go shoot a few hundred cops, wait a few minutes, and then walk around in the open once everyone's hate meter runs out.
It makes sense that you can evade the cops by evading them and ducking into a garage, but it doesn't make sense when your face appears on the hundreds of cameras around town and no one seems to notice that, hey, you're that vigilante guy that's been shooting people on TV.
At least, I'm really really hoping that's the case. Games need more consequences for your actions. I'll be disappointed if it's simply the result of a mission the character takes part in, rather than something you can trigger right off the bat by going on a rampage. It'd also be awesome if people around you happened to see you on their phone and called the cops. No game to date has given me the feeling that I'm a criminal who's on the run from the law; hopefully Watch Dogs will change that.
