Is This the New Gameboy?

With the run up to E3 (which starts in the next day or two) there's a shed-load of news appearing about what may make an appearance, including this article doing the rounds on various sites: Is This the New Gameboy?

I do wonder if the hand-held gaming platform may be ending its life as a separate device. Looking at the games offered by the likes of the iPhone, Windows Phone 7 and unfortunately to a lesser extent Android and even NGage, I expect to see this market swallow up the Sony PSP and Nintendo DS devices, perhaps with iPod Touch like derivatives for those who want something a bit bigger to game on.

Of course, only time will tell, and the DS is still the daddy of hand-held gaming, but just as the smart phone has been cosuming, or is consuming devices in other areas (PDA, GPS, Cameras, etc.) so gaming is becoming absorbed too.

When, I wonder, will we see a Nintendo phone? I'm guessing within 5 years.
