Before you worry about pricing, understand that DirectX 10 requires Windows Vista in order to operate. If you do not have Vista, you will not be able to use DX10 even if your card supports DX10. The games should use a DX9 path instead. Windows Vista will not be available till early 2007 and there are talks of it getting delayed further to the second quarter of 2007. Basically even if DX10 cards came out today, and DX10 games came out today, it would still be a good 8+ months before you can enable DX10 features because Vista won't ship till Q1 2007 at the earliest.
As for your questions, it will cost about the same as how much the X1900 and 7900GTX cost when it came out. In the 500-600 range.
It will support current PCI-E motherboards if the motherboards. There is no reason to assume otherwise and there will be a lot of PO'ed motherboard customers calling out for blood as well. Depending on power draw the only thing it might require is a power supply upgrade if your current one is not up to snuff.
