So far we have no confirmation of what rumor is right or wrong or even to what extent, to speak so strongly about Wii2.
Until we know it`s price, games and overall strategy, we can`t go that way. Well, rumors tend to make Wii2 go after Xbox360 and PS3`s market and be like them, but we all know that didn`t work for Nintendo for 2 generations, why would that be different now?
I still believe that Nintendo, knowing the casual market as it does, won`t be stupid enough to just forget a market that cared so much for them and go with full force after the core market.
Looking at 3DS carefully we can see how Wii2 will be marketed. Nintendo is going after the core market first because the core market is the one that needs to be convinced now. They can go seriously after the casual market after because they still resonate with them to this day.
And that`s what, imo, will happen with Wii2: Nintendo will firstly appeal to the core gamers because to expand their audience they need to make them believe that Nintendo will take care of them. The casual market will come after aswell, but probably later (after launch that is).
About 3DS, all i have seen in it`s marketing plan has been the emphasis on 3D, streetpass, street spot and games: the core behind 3DS.
So, so far, i don`t think Nintendo is loosing focus on the product as it all comes down to the gaming experience.
Why is is that Nintendo offers 3D trailers, for example? I don`t agree with Malstrom when he says the market doesn`t change, because it really does. And the PSP example you gave is perfect. Gamers, especially casual gamers, are in love with Ipads and such because it offers great content, diverse content and all consoles are giving more content because they need to appeal to that kind of people.
When gaming started we hadn`t that kind of market because there wasn`t a product as Ipad/Ipod, etc that offered an array of content/functions but now we have and people are expecting that from a product, especially when they have to pay heavily for it.
