Even after excluding Animatsu and Kazé titles, Manga UK will still have huge franchises like Dragon Ball, Naruto and One Piece which will no doubt continue to be successful - and from what Jerome's said, it looks like they'll be pushing the latest Dragon Ball Z and Naruto movies quite heavily too. New licenses like Danganronpa that, despite lacking critically, could also potentially earn a bit due to the original game's reception. Despite FUNimation dubbing Ghost In The Shell: Arise, I expect that to be safe as well, due to Manga UK's long history with the franchise.
Losing FUNimation isn't good though, especially given how early series' are licensed in their life time and with the biggest players in North America already being close to other UK distributors - Animatsu having close ties with Sentai Filmworks and outside of Madoka, Aniplex seems pretty happy to deal with Anime Limited and MVM. I'll be very interested in seeing what happens next.
Guess I might as well import High School DxD New now though, unless a company here is going to announce a release soon.
@britguy - A "FUNimation Title" is likely a series that FUNimation Entertainment obtained the UK rights to and would have normally sub-licensed those rights to Manga UK.
