RV 520 also available in AGP?

According ATI Power, ATI could release a R520-based graphic card in AGP format too, not only PCI Express. For such a purpose, they might use their Rialto bridge ensuring hardware conversion PCIe <-->AGP.
If this is true, it would be a good news for us, we could enjoy new generation graphic cards while waiting for Apple to finally move to PCI Express.
Thewebsite HKEPC is publishing a confidential screenshot describing ATI GPU roadmap, and indeed R520-based graphic cards are apparently planned in AGP format without Rialto bridge.
