Nintendo DsI

I'm sure everyone has heard about the DSi by now. It's an improvement on the DS lite. I really don't think this is going to work out. Millions of people already own DS's and does Nintendo think we're going to go out and buy new ones? The cameras are kind of cool, and I like the new look and Wii-treatment but I think Nintendo kind of pushing their luck with this. I hope this doesn't lead to DSi only games are I'm going to have to buy it...
