Dissapointing for me is when The Creative Assembly makes a shite Dynasty Warriors clone, when Lucasarts cans their planned (and nearly done) graphic adventure games so they can better position their Star Wars crap, when one of the best 2D shooter teams ever (8ing) hasn't done one in many many years because those crap anime fighters are so damn lucrative, when SNK makes fewer 2D stuff because their staff is too busy on 3D versions of Metal Slug and KOF.
Is the Wii the best place for a game from BHG? Perhaps not, but I won't be fully dissapointed, and I might even be somewhat optimistic about it until I know what the hell it is. Bad ideas can happen on any platform, and I won't condemn anybody until all the facts are known.
The Wii is set to have a scarily huge marketshare, I don't believe for a moment that there won't be anybody willing to buy or make games that cater to more then a casual audience.
