Actually we import most of our games, since we actually do tests against physical carts. Daz imported at least 4 or so DSi carts for testing, and I myself buy my games from either eShop or physical. Works best in the long run. And we don't need an out of region console since region unlocking home is fairly easy. Plus there's plenty to be obtained from the firmware on stuff in the header as well.
Also, I'm not sure 100% what you're blabbing about with Gateway, but if you're trying to say everyone is just leeching off Gateway's features, you aren't wrong to be honest. I'm personally highly doubtful anyone else will ever invest enough time into another arm9 exploit, and ReiNAND flat out said they're waiting for GW. From GWs standpoint, there's no winning move between somehow obtaining keys (if they can) or a new arm9 exploit. Either will be stolen. In any case, this thread isn't the place for discussing that.
