Could be, but it's pretty elaborate. I just watched all 45 episodes. His website had the originals, and youtube had the newest ones. Two of the videos on his site had broken links too, which is either the mark of a true personal site or a really clever viral campaign.
The whois on scottyiseri.com shows it was registered in 2004.
Of course, it's possible that MS approached him and they did a fake episode for the 'firing'.
I figured so, but I'd never heard of it myself. Still, I'm sure some of Microsoft's reported $90+ million advertising budget could have convinced Scotty to fake a video.
It would be pretty clever of them. Even we Hacker Newsers are apparently prone to rubbernecking enough to get this on the front page (really, guys?). The Bing references are subtle enough that it doesn't feel like product placement, but prominent enough that people talk about it (like many comments in this thread).
