Hey Jiyko, I think it is a very fair question and though I will not give an estimate for the reasons I have mentioned I’ll try to give you a better idea of how far off I am. It will certainly not be in a double digit number of months and I have completed most of what I want in the update. I think probably the best I can do is to list what I have made so far and what I intend to add before the update is done.
What I have:
- Cover system, including accuracy and dodge
- modular skill system including the sample skills Fire Laser, Overwatch, Heal, Explosive Shot, Sprint and Mind Control.
- advanced AI built into the skill system where the AI decides the best skill of all availible depending on the situation. Added for Fire Laser, Overwatch, Sprint and Explosive Shot.
- Basic VR support with a simple VR level
- Added several awesome creative common meshes for example games, including environments, units and weapons. Skeletal meshes have been rigged by u/Bankworthy.
Left to do:
- Make a good looking example level demonstrating the cover and skill system, using the mentioned creative commons assets.
- Adding a few common features to the VR level, including teleportation.
- Extensive testing and bug fixing of the new features.
I hope that gives you a general idea. I have far less remaining than I have done, and I will try to stop myself from coming up with new features to add (and especially my recurring urge to reinvent something I’ve already made 
). If you want to have use my cover system before then I’ve detailed the method I used in a post here. Afraid it will be difficult to make it to Cali and GDC this March, but thanks for the offer! I’ll be enjoying the icy winds of Norway’s west coast instead.
