I think that as Reggie said more than once, Nintendo is in competition with everything that takes consumer`s time: TV, movies, music, consoles, books, etc.
Personally i don`t see smartphones or tablets eating Wii or DS/3DS' market. What i see is Wii lacking software both for harcore, but more surprisingly, for the casual. DS sales also declined because of this and because of 3DS entering the market. 3DS still has to make a move on the casual front before we can say the market has fled. Nintendo still hasn`t made a move (excluding Nintendogs+Cats) and i already see everywhere that it`s losing that market. What game of any relevance has 3DS to offer to that market so far? Let`s wait and see.
Honestly, i do understand Nintendo trying to bring first the core before the market being flooded with casual titles and making it unnatractive - at least that`s my view -, but couldn`t those two markets co-exist if they had games for both since the very beggining?
That`s what i hope to see with Wii U from the start: Wii U and it`s controller have an enormous potential to appeal to both audiences right from the get go. Something that Wii nor 3DS had.
The "tablet" controller has the interface that can satisfy all consumers. Used wisely and it could do wonders.
Overall i think that Nintendo should greatly increase it`s presentation on consoles. Make it more stylish and accessible and if possible customisable: let me choose what i want to have in front me not just in terms of items but in how the template looks.
eShop does need improvement and i hope that Wii U has something that connects itself and it`s games to social networks. For example: putting your achievements on facebook or just your activity, uploading that awesome moment in a game to youtube for everyone to see.
If anything Wii U and 3DS should be what you want it to be for you.
