In order to justify the development of HD games most third party publishers have to release these games to the PS3, XBox 360 and PC; and if they're developing a game for an add on device (regardless of the platform) in most cases the game has to be playable using the standard default controller. When you combine these two things together you will probably come to the realization that any game made for these add ons will (probably) need to support a conventional controller, project Natal, Sony's wand controller and a keyboard and mouse set up; which essentially makes it unlikely that many third party developers will support the add ons, and even if they do few will produce games which make use of them to do anything meaningful.
