The console race is created by the fans...it doesn't matter to Nintendo unless they make money
With that said, I've voiced my support for a handheld/console hybrid before. Nintendo no longer has the capacity to maintain both a handheld and a home console by themselves and they obviously don't have the greatest luck with 3rd parties. This would allow a steadier stream of games as well as appealing to two markets simultaneously.
