Lets not forget the hardware is weak. It won't be long before the game reviews come in showing how dire they run on the big screen. We will see horrible aliasing, limited textures and a huge number of missing features. The heavily compressed cartridges will probably be slow to load. After probably good launch numbers reality will hit the consumer that this is another over-priced ultra low spec system of limited performance. It will struggle to sell and even Nintendo's brilliant games won't be enough to justify the high purchase price for most people.
It may become fashionable like wii and sell despite its limitations and to be honest looking at forums there does seem to be a lot of enthusiasm for it so that is possible but I think for the mainstream clued up gamer we know the only thing that will justify its purchase will be Nintendo's own games and until it has a good library of such games its probably not worth buying. Third party games especially ports will be awful.
However for those who want 360/ps3 performance on the move there is more justification. I'm not prepared to pay £40 for a skyrim cartridge just to play the 360 version on the move and it may well be only a few such games are released before low sales mean publishers abandon doing such games.
