FUD Zilla claims ATI may be trying to confuse both the press and its partners about its upcoming products so its competitors (NVIDIA) have a hard time guessing what the company is up to:
This is why ATI only managed to take Nvidia’s crown once with the R300 and only got close so many times. Nvidia always had its backup scenarios, as it knew what ATI was doing.
This changed with AMD and with personnel changes inside AMD's graphics division, as it looks like ATI’s primary goal is to confuse the press and partners about its upcoming products. Once you do that, Nvidia is in the dark and this is what ATI has to do in order to take the crown back.
Just look at 2007. We dealt with R650, R670 and R680 codenames, different specifications for the R600 PRO and so far Radeon HD 2950 and 3870 names for the RV670. No one really knows what is right and what is wrong anymore, including Nvidia.
