We would like to release the game on as many platforms as possible. Currently we could port the game to OUYA (we own some OUYAs!) so if we’ve got time, we may release the game for it at some point.
Nintendo 3DS would be nice, but would require a lot of work. We may release the game for the New 3DS if Unity ends up being compatible.
Developing for Xbox 360 and other consoles is just too expensive to develop for nowadays. Licenses are expensive so developers stop developing for “old” gen, and concentrate on current generation consoles.
