Hello Marco Simionato ,

As far as I'm aware, Studio 2019 should work with the current available filters (we offer support for all 'MS supported' Office versions).
Our support team has not received any complaints or specific support requests so far regarding the new Office 2019 release.
However, I think its fair to say, until Office 2019 becomes more 'mainstream' and extensively tested in 'real world environments' we won't be aware of any possible issues. There does not appear to be any new features in Office 2019- as these were already added as part of the changes offered in 365.
From a personal (and cautious) point of view- I would probably wait a few months (if you can) before upgrading-
especially as many clients will also wait some time before making a conscious decision to upgrade from a trusted version.
