It's already revelated that it will be on Wii(Ware) and it's not Swords&Soldiers2.http://www.ronimo-games.com/forum/viewtopic.php?f=3&t=706&start=10
And who made them do the revelation? Me! HaHaHa!
Maybe it will be in Space with rockets and robots.
Just look at the christmas card and the video.
Even if the video was a joke, what if it's a little hint inside?
