Is Inter Milan almost guaranteed to win Serie A?

[~O.N.E.~]

With the recent ruling, Inter Milan heads into the new Serie A season as the defending champions. With that, it almost seems like they are guaranteed to win it again.

Juventus: demoted, with a 30 point penalty (which almost guarantees two seasons in Serie B)
Lazio: demoted, with a 7 point penalty
Fiorentina: demoted, with a 12 point penalty
AC Milan: 15 point penalty and disqualified from both UEFA events

With the new Italian league, the only team that can really challenge Inter is Roma, as AC Milan most likely will not be able to overcome their penalty.
