Yes, it was a Dreamcast game that wasn't completed, though most of the music was done, and you can find the CGI intro online. The artwork showed the original Fire Leos and the Earth creations Gauntlet and Vambrace together with the new Fire Leo VI which looks like a hybrid between the Fire Leo and the Vambrace.
There's a rumor floating around that TechnoSoft is rehiring staff and wants to return. TF6 would be their first title for an un named console.
I have the Gold Pack One, but I missed out on the Gold Pack 2. Ebay will cost me around $100. I blame myself for thinking I would pick it up later back when it came out.
I liked Einhander a lot (my copy was damged by a friend). I also loved the Aleste games on the 16 bit systems too.
