Tomas has an opinion editorial on the gamesite Gamezebo:

It is a busy time for new consoles. This spring saw the launch of Nintendo’s new games console, the 3DS. Nintendo has just announced that a successor to the Wii is due soon, too. We’ve also had the news recently of Sony’s PSP follow-up, currently codenamed NGP, or Next Generation Portable. ...

But the world the 3DS was born into is not the world that the DS knew. This is the post-iPhone world, and all the rules of the game have changed. The question is not so much who will win between the 3DS and the NGP, but can either of them stay relevant in a world dominated by the mobile phone? I’m not sure they can.
