I don't buy into the rumors too much, the only thing that sways me is when Nvidia and AMD have products in reviewers hands that can be compared, I buy my GPUs based on bang for buck for the types of games I play, no loyalty at all...
I think AMD moving up their launch date is reaction to NVidia's release dates for the 1000 cards. Hope both of them have strong products so that we consumers have a good choice, and also so prices are competitive, in the current gen there hasn't been very equal competition, and the price for the same GTX 970 I have has stayed roughly the same since I bought it 18months ago...
