This is what i saw in the email:
Tomorrow is the Last Stream of Copa! Help Us Capture the Moment!
This is it! The last time we will stream Copa! Help us capture the moment by joining us live in the test build on the US server during tomorrow's Twitch stream at 11am PDT. We will be coordinating some epic moments to record for posterity as we begin to move on to the Kickstarter art pass! All art will be reverting to what we call "whitebox" stage. Behind this curtain we will be preparing the final art for the playable mockup, with the grand reveal happening when we unveil the Kickstarter! Want to join us in the build before it changes? Upgrade or purchase a
Newcomer Pack so you can get access to the Copa zone before it goes away!
THMPR encounter build coming!
The next demo will have the whitebox version of our THMPR encounter! Protect your THMPR in this first draft of the planned demo encounter! As part of this, new temporary whitebox terrain will replace Copa that is better suited to our gameplay. This is why we want to create some fond memories and say goodbye to the old demo level tomorrow on stream! We would love to see you there!
I think they mean this whitebox terrian replaces current copa at this stage and once the kickstarter is revealed then a better one could replace it from my understanding and it will be a surprise \o/.
Plus the stream needs a rename to something else like
Stryke Reapers assemble (Copa v1 last hope)

This is true reaper force, what if the group sneak attack all walk behind some tsihu and half use the scan spike and the other half use the plasma cannon wonder how that could look ah and another time some co-ordinated thumpr drops! perhaps on top of tsihu do they get squished?
