You're missing the point entirely.
ENTIRELY.
Nintendo is a big name company, and when they want to reveal a major product, they do so with press release. They have one of their bigwigs trot out to a room full of reporters, they reveal the product, answer questions, show a demo, and finish the interview.
You'll notice that if Nintendo is going to reveal a product that they've "never made before" that chances are they will PROBABLY back it up with A) a press release and B) a marketing push.
You forget that the only reason we know about the Konga controller is because it's being released in Japan and we have access to websites that can get the information about it and show it off to us.
Nintendo doesn't consider that kind of table-scrapping a press release. And if they are so confident in the product, and if they are going to surround it in mystery by saying it is "something we've never done before," you can bet they are going to open with a bang on the product.
So a few measly pics of a controller and some blurry screenshots from a game that isn't even translated because it's in ANOTHER COUNTRY is going to cut it for them as a viable form of press release.
It's like when a game gets released in Japan and we know about it, and then two months later Nintendo says they are "releasing a brand new game in America!" like it's something we've never seen before, and we end up seeing that it's just their news release of the translated game we read about two months ago. Just because we knew about it in advance doesn't mean that it's been officially revealed to the public.
But whatever. If I'm right, I'm right, and if I'm wrong, I'm wrong. But I really wouln't put too much stock into Nintendo. We've seen time and time again that they delay products and release things that we knew were coming.
So I really, REALLY wouldn't get your hopes up for something truly astounding, like an online strategy.
