Well, TX websites and activation system are already going down, so things are going much more faster than we expected. It was a matter of time, anyways.
Nintendo will hunt down mostly every reseller of the TX chip, and also group that takes the dumped code from the chip to produce it themselves. As quick as they become barely known, Ninty will be there.
As long as the amount of money genereted is big enough to risk a few years in jail, you'll have chips and support. Once the sales start to go down, say goodbye to that.
