Konami Working on New Suikoden RPG?

A new trademark has revealed that Konami could finally be working on a new entry into its Suikoden RPG series. Apparently the developer has registered the name Suikoden Tierkreis for the North American market. Obviously this does not necessarily mean the game will ever become a reality, since developers can always let trademarks expire if plans change, but it certainly gives hope for those wanting for something more following Suikoden Tactics and Suikoden V on PlayStation 2.

But what format could it be on? Obviously the series has predominantly been on Sony's PlayStation formats, starting with the PSone before moving over to the PS2 and eventually PSP with the Japanese-only release of Suikoden I & II. However, there have been rumours pointing towards a possible Wii version, so who knows...
