Did some digging and found this:
Additional Permanent Employment Visas: The U.S. currently issues around 140,000 employment-based visas each year. Under CIRA, the U.S. would issue 450,000 employment-based green cards per year between 2007 and 2016.[8] After 2016, the number would fall to 290,000 per year.[9] Under current law, LPR visas going to the spouses and children of workers with employment-based visas are counted against the cap. Under CIRA, these spouses and children would be removed from the cap and given legal permanent residence without numeric limits.[10] Historically, 1.2 dependent relatives have entered the U.S. for each worker under employment-based immigration programs.[11] This means that some 990,000 persons per year would be granted LPR status until 2016 and, after that, 638,000 per year.

So if passed with these numbers, PD's may become current again in 2007.
Ofcourse this is the Senate bill, on passage they will have to consolidate it with the house bill and then send it to president for signing.
