I am guessing you are in luck with IOE receipt number! expect it to be approved soon!
I have asked NVC and they gave me below reply through email
"Based on your USCIS receipt number, your case benefited from a pilot electronic process for the I-130 petition. USCIS reviewed and approved your petition faster than average cases of this type as we develop the fully electronic transfer of data from USCIS to the Department of State. We thank you for your patience while we continue to refine our process with these electronic petitions"
Same here. We received IOE also. What service center are you? My SC is Nebraska.
I asked few of my friends about this IOE and most of them got approved for 2months only.
