I mean, Nintendo's gonna find a way to block these carts if they could do it the original DS carts. How exactly will we update? Will the cart still be backwards compatible with DS lites? Similar to the R4i Gold working on a DS lite. (For this to happen, it won't be the same size as a 3DS cart. i.e, it will be missing that extra bump on the edge of one. If it IS backward compatible, then we will likely update via DS lites or unupdated 3DS/DSi, much like we do now. Any other ways I haven't thought of? Updating through DS lites and unupdated 3DS/DSi seems to be the only method right now.
