Rumours about Nintendo entering the mobile phone arena have been floating around for what seems like years now but the company's US main man Reggie Fils-Aime has effectively quashed such speculation in a recent statement to the New York Times:
“Telephony is not in our wheelhouse. It's not something I anticipate us getting into."
Hardly a massive shock; it's clear that Nintendo is good at making games machines and the company is well aware that trying to appeal to a different sector of the market can often backfire (just look at the PSP's early life).
As much as we'd love to have a DS-successor that plays games, makes phone calls and even washes our dirty underwear, for the time being all of Nintendo's products are focused on one function, which is probably a good thing.
