Nintendo DS 2 to be unveiled at E3 2008?

Hirokazu Hamamura the head of Japanese gaming mag Famitsu’s parent company is predicting that Nintendo will unveil the next-generation DS at E3 2008 this summer. So why are we positive on this rumor? Well it is not made by some anonymous and self proclamatory Nintendo employee but by a businessman who heads Famitsu the leading gaming mag in Japan. Hirokazu has not commented on the hardware or cost.
So how would you like to change the Nintendo DS? I am a proud owner of a DS Lite since quite some time and here is my wishlist for the DS 2.
1) Bigger screens
2) Powerful speakers
3) A mobile phone attachment. The DS as a mobile phone is a god send gift. But again it is a bit too much to ask.
