XT and Pro version
If our source is correct, AMD should be shipping RV670 to its board partners next month and it looks like two different models will be available from launch, the RV670 XT and the RV670 Pro.
Aparently the RV670 Pro will be available in three different SKU's which could confuse things, but we'd expect a GDDR3 and a GDDR4 version at least, since this should be the cheaper version of the two.
The RV670 XT cards will be made by AMD while the RV670 Pro cards will be made by the boardpartners themselves.
Hopefully there will be enough cards ready for a hard launch this time, as frankly, we're sick of paper launches from AMD.
