(Alright, I did steal that headline from something similar on fark.com)
So, remember when the DS was announced, it was also announced that it is a different product line then the GB series, and that GB will still go on? Well, thats not the case anymore. Because of the 'Wild Popularity' of the DS, N figures releasing another GB wouldn't be the best idea. But, I think thats a good thing, I remember when they announced that the GB would continue, most people bitched about them saturating the handheld market and all that, and now they arent going to do that.
From 1989 with the original GB, to 2005 with the Micro, the GameBoy name had a long run. Wii'll miss you.
