No one knows for sure that Nintendo's update intentionally blocked the card.....would be kind of hard to block until they get their hands on it and see how it has expoited the cartridge slot.....if Nintendo knew they had a gaping hole in their cart slot security why not fix it prior to now and render things like gateway unuseable. If gateway is a decent product then it will be updateable and it will likely take some type of hardware modification to permablock the sucker.....we won't know until we get it but I am stay on 5.x for now. My guess is gateway is working on 6.x update for release date and not wanting to tip their hand to Nintendo. As long as the thing can be flashed their is a pretty good chance they will keep it working. In the past most ODE type products like wiikey, wode, xkey have been totally undetectible to the host system because they appear just like real hardware....heres hoping gateway is similiar. If not then I will use it on 5.x for a number of months to play with the current library of title's I don't own and hope an update or another product fixes the problem for 6.x.
