I reckon there is a reason. Every title Funimation have announced this past year is from their Kadokawa deal; The Betrayal Knows My Name, Good Luck! Ninomiya-kun, Gosick, Hyouka, The Mystic Archives of Dantalian, Nichijou, Omamori Himari, Record of Lodoss War, Scrapped Princess, Sekai Ichi Hatsukoi: The World's Greatest First Love and probably many more (perhaps even The Slayers Movie & OVAs).
All have been confirmed region locked and are not streaming for the UK, so it's quite possible that someone in the UK could have a similar deal so Anime Limited for example since they and Kadokawa get along pretty well.
Id love to see many of these titles make it over here in particular Gosick, Loddoss and Scrapped princess. I would imagine they would be straight forward releases in that the dubs and subs are already done so they could just use Funimation masters.
