No need to get excited until Asia works out how to run these on new hardware. I doubt this news will change anything in the scene as far as ROM dumping goes as Legacy don't sound interested in sharing information with other groups about their dumper software, and rightly so i guess.
If you remember a similar thing happened with DSi Roms when Legacy showed off their custom dumper. As far as i know there's still no public DSi dumping tools available outside of the elite, and only a couple of groups that can properly dump them. So most of the "scene" that Legacy refer to in the nfos probably wouldn't be able to help dump 3DS games until software is shared as they don't possess the skills needed to create their own. No disrespect intended, that's just the way it is.
If you take that into consideration it could be a while before you see a 3DS scene that extends outside of the elite.
