I just re-downloaded the 757 about 3-4 days ago and my files (-200 and -300) read 4300. I accidentally deleted them doing some HD cleaning so I went back to redownload and now the files are both 4400.

The installer reads as 757 Version 4.4 during install so it looks like it has been released, only it has not been reported yet. :)

Somebody please correct me if I am wrong.
