I have to say I feel sorry for anyone who just forked out for a new video card, because you can guarantee that in the next couple of weeks there are going to be big changes. It was only a few days ago that AMDATI did the big HD 3800 series release and there is already news of a HD 2600 series replacement.
The new series, which you could have guessed already, will be titled the HD 3600 series, and will come in 2 flavors. The first having 512 MB of DDR2 (they still make that stuff?) and the second will be a 256 MB DDR3 version. It isn’t known yet if they will keep the old branding of XT and Pro, but considering the introduction of the 3850 and 3870, I would guess them to be the 3650 and 3670. The new series will based on the ‘RV635′ GPU and will support DirectX 10.1.
Apart from that, there is also talk of a 2400 series replacement (I guess the 3400).
