I was reading the article about how THQ isn't worried by GTA V's trailer and in the article it talks about GTA's radical shift in tone from San Andreas to IV. And that made me think that the shift in tone wasn't all that radical as everyone really made it out to be in my opinion. The dark humor was still there, the scathing social commentary intact, and the deep storyline filled with compelling characters was kept. The only radical difference in tone was in the visual department with the darker, gritty graphics.
Anyway that's just my opinion anyway.
