The rumor never states that Stars is a launch game.Actually, its not even implied.It just says that it will come to it.Everyone on the tgread was actually discussing that Winter was actually a good time to release it.And as for the dual screen thing, the game interface could be easily redesigned to work on a single screen.I mean, as far as I know, the second screen is mainly just a glorified menu.As for the mini games that uses touchscreen, that will require extra work and adaptation, but for all we know the Seitch could have a feuture that could replace the touchscreen and make it work(the rumored AR pointer).
So yeah, if Stars isnt real, those are not the reasons why.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
