I got mine today too, whoo hoo! Took about 6 weeks total: mailed it around the last week of Jan, and received 3 March. So four to seven weeks seems like the typical window of turn-around time, obviously dependent on the method you use to send in the rebate.
Now I just need a 3D projector, and I can actually watch it. You listening JVC? Start shipping that backlog to AVS!
