Nintendo's president admits regret in not working with outside companies more during Wii's reign...

In a speech to investors in Japan, Nintendo president Satoru Iwata has expressed personal regret in not working with other companies more in order to promote the Wii console in its later years.

"I now regret that we didn't tie up with someone outside the company to market the Wii. If we had done that, the fate of the Wii might have been different. Now I am aware that we should not rely too much on ourselves. You will see what I mean by this when we market the 3DS and the Wii in the future."

Nintendo earlier revealed that sales of the system was down 25% during the last fiscal year. While the wording of Iwata's comments far from indicates that Nintendo are ready to abandon the Wii, the company has already confirmed that it will unveil the first details of its next-generation this June.

Here's hoping Nintendo gives Wii owners a little more incentive not to think about the next generation too much at this E3...
