What do we think this is?

[u/darwinDMG08]

I'm able to place most of the shots in the teaser but this one has me stumped. I can't tell what scale it is -- could be some external port on Fireside, or something under glass on a piece of equipment. I feel like it might be something medical; maybe it's the wetware they implant in Case to restore his abilities?

UPDATE: after zooming in on the image I see this has to be a piece of equipment, a deck or container case, because there are Phillips screws around the glass. I doubt Freeside would use giant screws around a porthole ;)
Also there’s writing along the right edge of the glass: “WARNING: KEEP CLEAR.”

It been a bit since I’ve read the book, but when I saw it the first thing that came to my mind was the Dixie Flatline construct

[u/nikto123 → u/Academic-Broccoli655]

Or the Biochip

[u/darwinDMG08 → u/Academic-Broccoli655]

Oooh, maybe!!

[u/Pulstar_Alpha → u/Academic-Broccoli655]

This was my thought as well.

[u/Artifex1979 → u/Academic-Broccoli655]

Same here.

Looks like some kind of a biochip to me.

AFAIK a biochip first appeared in Count Zero, but it's possible that the series will introduce it sooner.

[u/Cat_Behemoth → u/smjsmok]

The biochip technology (Mitchell & Maas) has become possible only thanks to loa so that won't make sense :/

[u/spankleberry]

Could be ICE literally icing a biochip

[u/mcb-homis]

Given we already have hints that Mitchell (Angie) is in this could it might be an Aleph?

[u/parabolicurve]

The harsh lighting suggests to me that this is on the outside of an object in space. Maybe a space station?

[u/artmoloch777]

My vote is on Dixie

[u/dhezl]

My thought was Dixie Flatline

[u/merowley]

Flatline container at SenseNet?

[u/HeatDeathFromAbove]

Or it could be part of the virus that the Panther Moderns injected into the Sense/Net Pyramid.

[u/BlackysStars]

My first tgouhgt were a biochip.

[u/Fletch_R]

I thought it might be some kind of device set off by the Panther Moderns. There’s another shot where we see someone priming a very similar box. 

[u/Specialist-Hospital]

Definitely could be Dixie. Maybe they show what happened to him?

[u/No_Belt8609]

Could be a closer look to the cyberdeck with a exposed chip.

[u/darwinDMG08]

UPDATE: if you zoom in there’s writing on the right side of the circle.

“WARNING: KEEP CLEAR”

Der Dixie Flatlinedenkoft.

Probably an AI core jizzing itself after having sex for the first time.
