Well Nisekoi anime was also announced early (like ~80 chapter). As far I saw, 12th episode is at 33-34th chapter, that's almost 3 chapters per episode and it's going to be only 20 episodes. So early announcement, doesn't mean they will go slow with it. They can go with lower number of episodes or just animate up to the last arc. Fairy Tail also went Ep1=ch1, ep2=ch2-3.

Don't think AnE was good example. First AnE is a monthly series, at the time of the anime announcement it had 21 chapters (5 volumes and half), while Nanatsu have 9 volumes and half. It was clear that AnE will be short anime, since it will catch up to the manga quickly. They went with 1 chapter = 1 ep most of the time (1 chapter have ~50 pages or 2.5+ weekly chapters). Yet even at that speed, it would have catch up to the manga quickly, so they prolonged it and even added not one or two filler episodes. Basically what I'm trying to say is that AnE was made with the idea to be slow and to not catch up fast to the point they want to start their original end, thus they prolonged the episodes as every way possible, that's why the the first episodes were chapter 1. But AnE felt so slow paced, that it was even boring at moments. If Nanatsu goes the same road, then it would be awful. Usually the perfect pace for chapter per episodes is around 2.75 chapters per episode.
