With the reveal and eventual release of the 3DS and its glassess free 3D screen, people are already talking about the wii's successor, or the wii 2. Many people are speculating that the wii 2 will have HD style graphics, but Nintendo has always been a game company that always delivers some kind of wow factor to entice people to buy their hardware and software.
When the wii was revealed, the wow factor was motion controls. However, looking carefully at the situation it seems as if Nintendo's back is against the wall in regards to their next wow factor for the wii 2. There is no doubt that the wii 2 will incorporate some HD graphical capabilities, but the actual wow factor will possibly be a more advanced version of the 3D found in the 3DS.
Hold on a second, wouldn't the wii 2 be unable to implement 3D effects because the older TV screens could not handle the 3D, nor could the consumer afford the 3D televisions that are emerging on the market? Those TV are also not glasses free, right? Nintendo is not about to make its consumers buy a very expensive television just to play its games.
There is a soulution to this problem, however. On a recent episode of RFN, host Johnathan Metts mentioned that the wii does not have five years left in its life cycle. But what if it does? Here is my soultion: Nintendo goes to the TV companies with their 3DS and says, "Here is how you make glasses free screens." The TV companies then adopt the technology, perfect the technology and then the market drives the price down for the consumer to buy the TVs. Nintendo would need atleast five years for this plan to work out to frutiton.
The end result would be similar to the 3DS, but on a much bigger scale and with HD graphics and higher resolution.
