Yes I would mind, because of many reasons.One of them being that Nintendo is the most unique company in the whole industry, and most of the time they are the ones that push the industry forward.And if they stop doing hardware, well, the industry will lose one of its pioneers in innovating(hardware wise).
But of course there are other reasons, like pride.Nintendo always was(for most part anyway) the developer for its own platform, and i want it to continue like that because i like how things are.And also Nintendo games are so good because they are on a hardware they made, so they know how to take the most of it.And well, lets face it, if you ask someone who is fan of Sony/Microsoft if they would mind them going third party, their answer would be yes, because they want their favorite companies to succeed on all fronts, hardware included.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
