While you might be calling it a little late to be releasing such a trailer, Tecmo Koei in Japan today released their Jump Festa trailer for Dynasty Warriors Vs on their Youtube channel. The trailer was first shown in December and covers pretty much all the basic gameplay elements you will need to know about regarding this release. The game is due for release on the Nintendo 3DS in Japan on the 15th March 2012, with a moderate to good likelihood that you will be seeing it internationally at some point.
