I hope they did.

pre-contract with Bari. I guess he won't come in the next 2 years. In fact he should stay at Bari another 4 years.

So this means tha he will be with juve in at least 2 years ?

If that's true it's the best news in a long time - Cassano is going to be the best Italian player ever. Think about the Juve team in a few years: Maresca, Rigoni and perhaps Cassano - Juve will soon win the third star for their shirt.
