Joining this thread. We are also way past the consular processing and at this point already received a green card via mail (IR-5 class).
Unfortunately it contained a mistake (not our fault), so we filed I-90 to make a correction and issue a new card.
It's been 7 months for us and no news quite yet.
If USCIS processing times are accurate, then we have another 7 months to wait; but I am not sure if we can trust those estimates.
If we hear anything, I'll post the update here.
