Why would they give information? The expansion is probably not finished, it's on pre order and we got some teaser vids. Ofcourse, not very much information but the fact that everybody is discussing it/ guessing what it might be says enough.
With 500 new people joining us in beta, I bet relic is more busy with keeping everything quiet, I'll bet you'll hear from them soon.
They could do things like take the jagdpanther, show some pics of it and give a small descritption of it. Do this for another unit 3-4 days later and then another.
They could give examples of how the faction is designed building wise. Show some pics of the base buildings.
The extreme NDA of alpha/beta is so stupid. They removed the closed beta and created a new one for an elite (RTN) group of people trying to remove the leaks. Now they reopen the beta/alpha and expect things to be different?...
Relic: be open with changes, just say they might change and that everythjing shown from alpha/beta is still under testing
