Hyperion will likely keep the sources but no longer have the licenses to the IP / trademarks in order to use it. At that point they'll sell it to A-EON who are on good terms with Cloanto and AmigaOS 4.x will limp on with new licenses. OS3.1.4 is another story however.
At the end of the day whoever the owners the same contractors will be involved. If A-EON get OS3.1.4 as well with permission and license from Cloanto the developers might even get paid
