What happened to Prologue's single missions?

I wanted to wait until the game was released to ask this question, as I know polishing the campaigns has been the primary focus of everyone's energy, and I am pretty sure this is much lower priority.

What happened to the single missions that came with the original version of prologue? Are they going reworked at some point? I miss the simulator Gauntlets.

I was not referring to Prologue campaign itself, I have played through that several times over. I am referring to the single missions that used to be in the tech room simulator, like the Arrow Gauntlet, the Hellcat V Gauntlet, and the Thunderbolt Gauntlet.

That's sort of what I figured.
