Nothing too surprising from a quick read, but some may find it interesting to read the summary of financial results and other descriptions. No real insight on any possible new ship builds (only a general description of how the possibility is constantly evaluated).
From the disclosure, they clearly view Oceania as a different product (upper premium, rather than luxury) and there is no indication of any intent to "merge" the two lines. It is clear that Regent depends heavily on the Prestige executive team (note risk factor re: Del Rio being the most key executive for Regent).
If you want to be voyeuristic, you can even read the employment agreements for Del Rio and Conroy, and there's explicit disclosure about the amounts and types of compensation paid to senior executives.
