Thank you all.
eb2007: Yours should be around the corner. USCIS seems like reviewing the EB1 in cycles of every 15 days. There were 4 approvals on same day fortnight before, and if you see Trackitt.com, there were 4 more approved yesterday itself.
The key for me was, I completely and honestly stopped thinking and expecting it by indulging myself in some other important things in life. And it will come unexpected as a surprise.
Also, keep checking your spam folders too. All my other correspondence with USCIS came in my mailbox, but this approval one had to go to my spam folder.
Good Luck,
