Percentage

Could the team make a percentage of what it's done already? This way people can see the equation progress(time) if you understand what i mean.

There is no real percentage of the level it can be done. Because they might add in some of the community's ideas into the planning, hopefully.

Something between 1 and 100%
Good enough?

It's pretty much the same as asking when will 1.3 Full come out.

Even if he told you the percentage of the progress....

1. He could be completely wrong
2. It wouldn't matter, because it still would not be finished

I'd say it's likely between 50-60%

They should have all the core maps finished and most of the models/animations.

At this point they have to develop a new advanced melee system and/or tweak the beam system.
