For whatever is worth, it seems that Nebraska is currently processing cases around April 8, so still consistent with a 8 months processing time.
No need to create another entry, Nebraska on December 11 seems to be processing cases around April 17, 2008.
Again, just updating my last entry. On January 21st I see some activity up to around August 22nd, 2008. However, the bulk of the activity is much earlier, probably around mid June or so. The activity around August seems to be mostly requests for evidence. It seems they scan some cases ahead to send the requests for evidence and give a chance to the applicants to respond and get approved within the processing time frames. I don't want to keep my hopes too high, but it would seem like Nebraska is picking up some steam and processing a bit quicker. For now I will still hold to the 7 to 8 months expectation.
