So we have heard: DSi is incompatible with flash carts. I'm hoping for flash carts to work on DSi but if it wouldn't, it will be officially a follow-up of GB Micro. It's not that GB Micro can't handle the same power as its predecessors GBA SP and the original GBA. I think it would be a failure because if flash carts won't work with it, the DSi will have really low sales and people will prefer buying the Lite vs the "i". Also, some DS Lite games might not work with the DSi so that's another factor. Finally, most people think it's an unnecessary upgrade and they think it's more of a downgrade of the Lite. So what do you think? Does the DSi follow the DS Lite or the Micro?
