Well at this point it doesn't look like DC or D:OS are getting an Xbox version, so you don't have to worry about the genre, camera or gameplay design. Larian recently brought up the possibility of gamepad support for D:OS (
Good isometric RPGs with controller support?), which, if implemented, would make a console version possible. Last we heard a console version of DC was possible if they were able to secure the financing (see
here), but it has not been confirmed.
Have you considered the possibility that maybe some people like different styles of gameplay than you do? Perhaps these opinions could be just as valid as your own?
Maybe you should try something out of your comfort zone once in awhile, if the rest of a game looks good besides the camera perspective. I generally don't like first person perspective games, especially if you need to look around while moving in a different direction, but have tried first person RPGs that have been recommended in a few topics here, and I bought at least one I would have missed otherwise.
