They mentioned that the new anime series they have may already have English dubs, which seems to mean that they might be working with titles that have been released internationally, but not here. That seems to mean that some of these titles they won't be holding the international distribution rights to.
With that in mind:
-Deltora Quest (Just picked up in Australia, handled by DCI-LA)
-Pretty Cure (Airs in Canada, handled by Toei USA)
-Beyblade Metal Fusion (Broadcasters lined up around the world, handled by Nelvana)
-Kiba (handled by Neo-ADV)
-Megaman: Star Force (handled by Viz)
Potential new pick ups:
-Battle Spirits
-Mushiking
-Bakegyamon
-Fairy Tail
-Ape Escape
-Web Ghosts PiPoPa
-Shugo Chara
Series that have had other iterations dubbed into English without a known licensor:
-Crash B Daman
-ZoiRAB: Genesis (Viz technically has this, but they haven't spoken of it in five years, and have never released a single episode)
-Duel Masters (Bigger than Yu-Gi-Oh! in Japan, a relaunch could do well)
They could also be picking up series they've dropped in the past, like the fourth season of Yu-Gi-Oh! GX, Mew Mew Power, DoReiMe, etc. If they're truly desperate, there's always the 1998 Yu-Gi-Oh! TV show and movie.
As for why 4KiRAB doesn't have the Yu-Gi-Oh! 5RAB Jump Anime tour special, that's because of who owns the license to that. Unlike the usual Yu-Gi-Oh! anime that is owned by NAS, and Studio Gallop, that special is owned by Shueshia. The same goes for the other Jump Anime Tour specials, like the DragonBall, One Piece, Naruto, Bleach, Gintama, etc. ones. Shueshia deals almost exclusively with Viz Media in North America.
