The CompactFlash Association (CFA) and the group of supporters of XQD memory card format led by Sony Corp. and Nikon said this week that it had begun the development of XQD 2.0 memory card format. The second specification of XQD will utilize PCI Express 3.0 technology and will bring transfer speeds to memory cards to 1000MB/s, or about 1GB/s.
XQD 1.0 cards and connectors are already available in the marketplace. XQD 2.0 will leverage the same connector interface as XQD 1.0 interface for higher performance and backward compatibility. Host manufacturers and media manufacturers will be able to leverage the PCI Express 3.0 technology to serve the high performance requirements of this market. The new format will have VPG (video performance guarantee) capability with profiles capable of supporting digital intermediate formats such as ProResTM, DPXTM, and DNXhdTM. The XQD 2.0 will utilize PCI Express 3.0 x1 interface, will work at 8Gb/s data rate and will consume 5mW standby power.
“The XQD 2.0 format will enable hardware and imaging applications to leverage the performance benefits of the well established PCI Express infrastructure allowing for many years of higher performance and backward compatible products. The Video Performance Guarantee Features of XQD 2.0 will also widen its appeal meeting the needs of higher end video applications,” said Shigeto Kanda of Canon, chairman of the board of CFA.
CFA is targeting for the XQD 2.0 specification to be available in the second half of 2012.

"CFA is targeting for the XQD 2.0 specification to be available in the second half of 2012"
Is that correct? So you mean this will come in the next 6 months? I would be very surprised if that is the case as XQD has been out such a short time and has like what, 2 cameras supporting it currently.
Problem with this, and everything Sony touches, is its so closed and expensive. Sony like to control everything so they can squeeze every last penny out of you but in the long run these things always fail because no matter how good they are they will never come close on price, which is the real key metric to measure.
Betamax video, 1975
Digital Audio Tape, Mid-1980's
ATRAC Audio Compression, 1993
MemoryStick, 1998 includes: Pro, Duo, Micro (M2)
Universal Media Disc, 2005
Basically, if its closed and proprietary it will not work.
But its great to see what can be done in the future probably on some dirt cheap SD card variant. Looks like 8k at 120fps isn't too far away.

I think Anton means the specification will be available in the second half of 2012, not actual hardware supporting it. Once the spec is formalised, then give it another 12-24 months for actual hardware to be available.
In regards to closed standards, given its based on PCI-Express I don't think there will be much that Sony can close about XQD 2. Also keep in mind the entire CFA is also supporting it, so if anything its the opposite of a closed Sony standard, so hopefully this one will actually get off the ground.

That makes more sense, I thought it was something Sony had come up with itself but if Canon and alike jump on board then should be a pretty cool card.
Just hope prices aren't crazy!
