And why shouldn't they cancell it. If 3dfx gives up on the 6k then the NV20 has nothing to compete against. Why should nVidia spend anymore time, energy, or resources on it.
I also think it was a good choice for 3dfx to drop the 6k and put all their efforts in to Rampage. Since the 6k is/was obviously giving them so much trouble and they've delayed it 3 or 4 times. Now they too can forcus more on their next product.
