I GOT IT. I just got the vegas 6 from B&H. Here's some pictures:
Back part to the envelope:
Here's two pictures of the disk, tell me what you think, the orange tag on the envelope has the serial number. Bootleg/not/unsure? Do tell me.
I tested it and it works flawlessly so far and has some slight differences than the trail version of vegas which I've been using for awhile but have uninstalled it after recieving the disk. It let unlock the mpeg plugin so now I'm able to import mpegs as well.
So I'm just here to confirm that from what I see...it seems very legit and in working order.
So if you want Vegas for only $99 than go there...or else wait a bit for me to try it out some more. The link that TaranT has.
