See that line of thinking is just baffling. Sony was very quick to get all the details on the PS2 out early enough before the Holidays to stop people from buying a Dreamcast in order to talk them into waiting, that worked really well for them, why wouldn't Nintendo want to try the same thing, come out now with all the goods and say don't you dare waste all your holiday money on Microsoft or Sony crap we have an amazing product just around the corner. Well because there is probably some really baffling, head scratching Nintendo move coming that is going to deflate the hype train and they are better off holding that until closer to launch when they get people sold on hype and promises. Except that isn't the smartest move.
Even making the excuse they don't want to cannibalize their 3DS sales this holiday is false, again Sony had no issue putting all the juicy bits out about PS2 to strike the Dreamcast even though they were still very much supporting the PS1. Nintendo is just being Nintendo and my fear is the really hard to swallow piece of news that steals all our hype and crushes all our dreams is the real reason they are holding back.
