My DS has been broken for quite a while now and I plan to get a replacement for it soon. But with the release of the 3DS I'm not sure if it's a good investment now. If they start making games only for the 3DS then buying a DS now might not be a good idea. Some of the 3DS games appeal to me (like paper mario and Zelda) but it's quite a bit more money. So my question is, which would be the best investment?
