Considering what I have seen in the transfer window so far, I feel a back-to-back title for Inter this season. 
Inter doesn't need to be that much active in the market but the other top teams should be.
Juventus has changed their manager maybe but they still couldn't perform the transfer plans in their mind. Motta has a really difficult job to do because of that. My biggest expectation is from Napoli to make difficulties for Inter honestly.
Because they already have a great squad. Osimhen and Kvaratskhelia also are staying for another season as it seems. I don't see any offer for Osimhen because of his high costs. Conte is a special manager and he would know what to do with this power.
I think I have similar opinion with you concerning the club that's likely to win the Italian Serie A next season and that's no the current champions if Italy. Inter Milan won the league last season with much points difference and I expected the other top clubs in the league to be very busy in the transfer market this summer but that's not been happening. Juventus, AC Milan and Napoli though have changed their managers, but that doesn't necessarily make much difference if you ask me.

It is probably not going to be possible for Juventus to actually compete for the title. Because yes they were able to get a new coach. But they were unable to actually get the players that they wanted. Especially now it looks like whichever player they are actually targeting are getting hijacked by other clubs.
Napoli is probably going to have a result that is not good as well. I wanted to say they will have a result that is worse but compared to the last season they might actually see some improvements. But still do not think they will compete for that title.
Inter should have another good season. I think they are counting on the players that they already have to have a good result again. I guess as the same squad did work once, they are not willing to make any big changes.
