Although undoubtedly Nintendo offered a different type of interaction with the Wii, if you feel a little technological backwardness in the matter of graphics, where its competitors have taken the leap into the HD era and they are still at a level similar to that of the era of 128-bits.
Knowing that tomorrow Oct. 2 there will be a conference and Nintendo will confirm these (i think not) rumors that have jumped on. The site What They Play ensures that Nintendo is already showing what publishers would be an improved version of the Wii. Besides, says that would be launched before 2011, taking high definition and more storage space.
Supposedly, this would justify the increase in research and development that has been going on at Nintendo, we will have to wait for the conference to learn that much is true of all this.
