Additional Vessels

I think that's quite possible. It just feels a little strange to call that a 'wave' (though technically true any way, so eh).

lmao vorcha ship lmao. Better be staffed by asari trainers/guards.

Yah, OP. End game and other conversations suggest that not only the Quarian ark is coming, but Elcor, Hanar and Drell as well.

I wouldn't count the Batarians in to be honest. Not sure why someone would put them in an Ark, since they are majorly seen as terrorists.

The ark could've departed in 2186 during the Reaper invasion, but I don't think there weren't any kind of resources for it back then for a huuuge Batarian Ark.

Same about Vorcha. Low life expectancy and all of them are viewed as scavengers and suffer prejudice. It would be a good idea for a Vorcha to go to Andromeda, since y'know, they are immune to diseases, but I don't think they are intelligent enough to comprehend what going to another galaxy means and the whole concept of the Initiative. So, unless someone trapped some Vorchas and put them into cryo-sleep, Vorcha is almost 100% not appearing anymore.

I expected some automated supply vessels to arrive at some point. Maybe in a future DLC or game. I wouldn't send a few ships with bodies and not send some supplies separately just in case things happen on the way. I was surprised how much the nexus relied on the Arks to get up and running.
