I think the same thing happened in a few episodes in Zettai Karen Children although it was the other way around where SynergySP became the subcontractor and Gonzo took over the production for some of the episodes.
Hopefully they're gonna make it since I don't wanna see any anime studio perish... (Nope! I'm not an anime studio hater. I'm just being neutral though so that I could lessen the bash and hate, here and there. Thank you...)
And shucks, the one anime GONZO is making money from has now left their hands. Poor them.
Actually, Gonzo earns no money from Saki, despite the popularity of the series. They aren't on the production committee, which means that they get a fixed payment for animating the show (as opposed to any royalties/shared profits; after all, they aren't footing the bill for the series). As you might guess, creative control is in the hands of the sponsors, which is why Saki is so different from a typical Gonzo anime.
If downsizing was the impetus for this change, it'd make sense for Gonzo to pursue a release from the contract.
