That is correct for the first generation of chips currently being used in iMacs, Macbooks , Intel would not allow the option of a TB PCIe expansion card , specifically due to the fact that the DisplayPort had to be directly plumbed at the motherboard level and that would it be impossible to implement both PCIx4 and PCIe x16 .
However with the second generation TB chip which has been adopted and is being rolled out ( albeit very slowly) by the 3rd party OEM/ODM PC manufacturers , Intel will in fact allow a PCIe expansion card and to separate the 2 aspects.
The logistics of running both the separate PCIe x4 and PCie x16 ( DP) channels in some instances is achieved by a header on the motherboard - i.e the PCIe x4 is achieved by a standard interconnect into a PCIe x4 slot , the separate PCie x16 is via a connection cable from the card to the header on the motherboard. If the header is not available on the motherboard , the PCIe x4 expansion will still be available sans the PCIe x16 aspect for displays - which will be fine for many.
PCIe TB expansion cards are coming , how they ultimately perform will be the question.

Thanks Mate, duly noted and very much appreciated.
