Yeah, my thoughts exactly. The project's very, very late and Rockstar has thrown three more studios at it - a better sign than cancelling it outright, but it doesn't signify a smooth development effort.
On the other hand, despite their games being extremely slow to develop, Rockstar does seem to get a good level of polish on their games.
I`ll probably end up getting this. The bullet time mechanic is so much fun and is really only used by this franchise.
I know the change in theme is controversial, but I'm all for it. Rockstar excel at creating a unique tone. The quality is going to be there, so it'll definitely be fun.
