Wow... Most people here don't seem to get that only the DS MODE is "hacked", so you can only play DS ROMS on the 3DS, NOTHING ELSE...
But, I too hope, that there will be 3DS cards at some time. I mean, the DS game prices were already ridiculous here (39.99€), but 3DS games will cost 44.99€... WTF?!
(For those who don't have € but $ -> 39.99 EUR = 54.9942 USD / 44.99 EUR = 61.8702 USD)
Ok, some DS games cost less (maybe 34.99 or 29.99 but only after some time), but still... There are even PC games that don't cost that much and those might be even better (no idea, I'm no PC gamer).
Now I want to see news that the SCDS2 works on the 3DS (DS mode of course, anything else would be moronic)
