I saw the revised pages today, too. Everything makes more sense now. But the processing dates listed are useful. USCIS says to contact them if the current processing dates are past your priority date.
The only thing that bothers me is this business of a cut off date in the new immigration bill. Anyone with an application, employment or family based, that was submitted after this date will have to restart the process with the new system and be mingled with all the illegals applying. This cut off date is in 2005 with a pending amendment to change it to January 2007. I will be ticked if I get stuck having to reapply with illegal immigrants. The backlog expected from all the illegals applying is 8-12 years. I’ll be near retirement by the time I could get a green card with the way Congress is playing stupid with immigration!
Your situation is much different than mine. I can see why you're frustrated.
The dates I'm seeing for the I-129F say they're processing those received in Dec 06.
My petition was received in Feb 07 and has already been approved and sent to the Embassy.
The site date is wrong by a few months, so is useless in my much shorter duration case.
