I would suggest you not to buy any 3ds flashcards right now. Well actually there are some discussion going on at the Chinese forums saying that the team has found the exploits on 6.x. So, my theory is that they are waiting for the 1st generation cards to be cleared from thier factory before releasing 2.0 which I think will support 6.x, and I suppects that multirom support needs revamp of the cards too. That is why they are making "some scenario" to delay the release of 2.0 as long as they can until the 1 gen of cards are cleared(if you know what I mean

) . If you ask me why I came out with this is because based on the previous video by them, they did not show us the 3ds firmware version.
But all of these are merely speculation.
