Should be a good season this year in Italy. Juve arent quite the machine they were in the past but are still very good, and Inter, Lazio, Atalanta and AC all feel like they're improving. Roma and Napoli were disappointing last year, but if Roma can improve their defence and Napoli can improve their attack, neither are far off getting into the top 4 mix.
Key thing is, there seems to be a lot more teams that can beat Juve this year. Usually Juve ram home their advantage by only losing 2 or 3 games in a season to the top 6 or 7 teams home and away, while the other teams all take lots of points off each other. But I think any of the teams from 2nd to 7th would fancy their chances against Juve this year. They could easily get two or three more defeats than usual, which could open the door for a contender.
Personally I think AC could be the most interesting team this year. Great little group of young players there. They're not good enough to get in the title mix, unless something remarkable happens, but they could make the top 4 with a fair wind.
