Confirmed: Geth status

Not surprising. I agree with wright1978. Fan service is great, but it needs to make sense story wise. Besides, the Quarian/Geth conflict still needs resolving at time of Initiative departure. Future game maybe?

I feel like they've written themselves into a corner a bit as far as the Geth and the Quarians are concerned. If we somehow see them again post-original ME trilogy the game is gonna have to account for whether the Geth are alive and the Quarians are extinct, or vice versa, or both races survived -- and it sounds like the devs were really aiming for Andromeda to be an entirely clean slate, so they may be very hesitant to bring a "mess" (for lack of a better term) from the original trilogy into Andromeda.

They're AIs, they're established to be monitoring organics, curious about the galaxy and everything, wanting to grow and learn. I see no reason why they wouldn't install a few of themselves on board the Ark's toasters to get to Andromeda and report their findings back home.

Also, they're an amazing and popular race, much more worthy of fanservice than space babes Asari.

Alright, l'm curious.

While they have been monitoring organics, other than the heretics under sovereign there doesn't appear to the sort of aggressive invasive approach you are suggesting.
They've got their own goals(such as building a dyson sphere to focus on) & dealing with internal strife. Then there's the fact at the time of launch there's the most fanatical checks going on(such as in Citadel) because of the heretics attack that i'd highly doubt security would be so sloppy to allow them to download to the nexus. Also if we can't communicate back to Milky Way, how can the geth propose to do so.

I don't really care which race is more popular. From a lore perspective it makes perfect sense for the Asari to be present and it makes little sense for the geth to be there.

Alright. 

1. We know that the Geth were curious about the rest of the galaxy and infiltrated the Extranet to learn more. There could have been some programs that entered the systems of the Nexus and Arks and before they could pull out of the systems the ships launch, taking those Geth with them accidentally. 

2. We know the Geth let those who disagree with the Consensus leave if they wish. After Legion or observation data returned to the Geth Consensus, they decided to prepare for war against the Reapers. Some Geth could have instead decided to try to hide from the Reapers, so when they left they looked for the most efficient and logical way to do so and found the Initiative so uploaded on the ships as stowaways. 

3. The leaders of the Andromeda Initiative made a deal with the Geth. We know the leaders know things that the rest of the people don't like the imminent Reaper invasion and they would know either through Shepard or other information that not all Geth were like the Heretics. So in exchange for allowing some on board, most likely secretly to prevent a panic, the Geth would serve as the crew of the ships during the sojourn from the Milky Way to Andromeda while all organics were in stasis. 

Hmmm, I suppose those options could work.

But still, it feels a bit like shoehorning.

I mean how many Geth did you have in mind to be in Andromeda? It took the Geth centuries to build the numbers that they were in ME.

Of course it would require aggression. They would have to pierce council space in order to somehow breach the Andromeda security to get any platforms downloaded onto a nexus.
That's a whole order of difference from passive surveillance. I see nothing from the geth that would suggest a desire to pursue such an interventionist approach nor having individual nature to desire separating programs from the collective for ever.

The dyson sphere project is the absolute opposite of that

The long-term goal of the geth is the construction of a "megastructure", a massive mainframe capable of simultaneously housing every existent geth program, thereby maximizing their collective processing capacity. In 2185, the geth have already been in the process of constructing the megastructure for 264 years. Legion suggests the closest conceptual analogue is a Dyson sphere and, as it poignantly states "no geth will be alone when it is done." It believes that Sovereign promised the heretics a Reaper body to serve as such a megastructure 

Makes sense after there attack on the citadel there going to be at the bottom of the invite list.
