its more like that the show will start after the "episode missions" - its like a prologue.
Maybe you need to have completed those 4/5 mission to even see the next one on the 15th ? It does seem strange if they remove those first ones though.

If you watch the sneak preview to the show its the first 15 minutes of the show. There is something in the show that ties back to something that happens in the missons. So I assume they want you to play them so you can catch on to it in the show.
It gives some background to the first episode. If you watch the 14 mins preview of the Pilot you will see something that will seem familiar. And there is even a line Nolan says that you'll know exactly what he's talking about if you do the missions beforehand.
There are a lot more places online to watch shows than the TV websites.
I would be very surprised if they removed The Heist. I think they just wanted current players to see The Heist before the show airs, since that's how it happens chronologically.
If they do remove The Heist (and other Episode Missions), presumably they'd cycle back through them in a few months, when the TV show is done with Season 1.
