I dont believe I've ever personally said the controller can't be, at worse all I've ever said is that a fancy controller dosen't assure miraculous change in gaming. It's still a person's right to say they dont think it will be for right themselves. If I dont like the looks of something I'm going to say it, and one thing I CAN guarentee is that not everyone will be as nice about it as I've been.
But even then the fact that it's different isnt the only issue that puts people off from it. Like I said it's alien, it's been wrapped in a huge level of hype, and it's unproven. People react badly to things that are too different and if too many people react that way then nintendo's own attempt to bring new people will have scared people away under those circumstances it's up to Nintendo's PR department to try and change people's minds and get them on board, Nintendo has instead shown no rush to do so. Meaning that at best it can only change someone's mind if they play it which is less likely to happen if there are fewer people buying it.
I've said it before for Nintendo to reverse the way people have innitially reacted to the system they have to pull back from their overbaring "revolution" statments push their retro/backwards compatability game, internet content, and show some games already. Then you can spring the merits of the controller on people, this way it becomes an extra added value rather than a hinderance to sales.
