I don't want to give another eta in case we don't make it again, since that would be further disappointment.
Once we are 99.9% certain we'll be pushing more stuff out to show before the release.
Completion of the Sol Gate is taking longer than expected and is our next major milestone. With that complete we can finalise the first 2/3rds of the campaign and only have to worry about the assets required for the final mission.
The Terran fleet is ready apart for the Bastion and the Sol Gate, the Arcas and extension HTL models will have to wait for R2 as those are going to take a few months and would increase the delay to unacceptable levels now.
The EA is missing 1 model for the final mission. The Icanus won't be done till the next release as that model is proving difficult to upgrade at this moment. After that there's only a few minor things like a sentry gun and support ship.
The Vasudans, thanks to Dagger are in a far better position now. They are still missing major models but not for the first 30 missions so there will be no delay there. Major missing models for R2 are the Vasudan flagship and carrier.
The Shivans are good to go, only the Gania and Gigas need to be completed there for r2.
