The SD9 is released this week with a UK price tag of £1299.
This looks like Sigma's way of getting in on the market. I assume that they are selling the camera as cheaply as possible knowing that they will get their margin back on the lenses, as this uses Sigma mount.
I still do not regret buying into the EOS system as I have a nice collection of lenses for my EOS30 (including L series) which I can complement with a digital body when I am ready.
To anyone looking at a first SLR system though this is tempting, as it is priced about the same as an EOS30 body and mid-range slide scanner.
The test shots at dpreview are stunning.
