PCI Express and double layer for this summer

Sony will release during next summer a high-end PC model. we will not describe spec of this computer, but only few interesting points:
- ATI Graphic card PCI Express 16x
- 1 GB DDR
- 250 GB HD
- DL DVD burner.
Those arecomponents of a computer which are not depending on the processor/OS type; so components which could be present in the future PMG5 revision.
For sure, this summer PCI Express graphic cards as well as DL DVD burner will be available in large amount...
