It will be something awesome to have a new the fourth DS... I have the full collection of DS(s)... DS, DS lite, DSi... But if they made a new one i should but it
the only reason they made the DSI was to try to protect their games from the R4 card type things doesnt really work though if a person that owns one doesnt hook it up to wifi
There are ways to get around those R4/flashcart blocks.
I think the touchscreen is innovative for a handheld, they should keep that aspect. Now they need to focus on processing power, and MUCH improved graphics.
