I think the viewpoint will decide on the sales of Original Sin and reviewer's comments / player feedback. Personally I would want it in 3D like DKS with either 1st or 3rd person perspective rather than isometric. Dragon combat would not work with an isometric view.
If it were released on multiple platforms it would increase the player audience. Isometric view games are best suited to a PC where 3D suits anything in my opinion.
As you posted whilst I was editing my previous post - see my comments above about Dragon Commander originally being an experiment for Dragon combat in Divinity 3.
