I can't find a single source confirming new Egis to appear in the expansion.

[Averax]

They were scrapped, and i assume it was to devote more resources to improving the job's playstyle quality.

We're getting Egi glamour's though (you can make egis look like other egis, most likely including ones we don't have). So that's something. (but not till much later)

Personally, i prefer the ability to glamour them over having to choose the best of the new ones and ignoring all the others. But that's just me.

Edit: I found it posted in the thread they made to cover the letter from the producer
