While a majority of the above video is for Gamearts previous release of Ragnarok Odyssey which seems to be doing quite well in the Japanese market (and with any luck will receive an English localization sooner rather than later) and is previewing the upcoming online multiplayer patch for it, if you look at the later portions of the video say around the 2:30-2:40 mark, they have included previews of two brand new Vita games into it.
These previews do not offer much headway into just what style of games these are… but the first is by their development team PonKotz Troops who are developing a game by the name of Dokuro while the second is an unnamed title being developed by their Team Gajet development group. We are asked to stay tuned for further information, so expect news on these titles very soon.
