There isn't going to be a fork.  The screenshot shows that testnet is being forked, which is the testing environment only.  What's more it explains that the purpose of forking testnet is to test the next release of the Dash Core wallet, v.12.2.  Once the testing is complete, the network will simply upgrade, which is really easy and can now be done very smoothly thanks to sporks and Sentinel.

So hopefully you can understand why your post appeared alarmist.  Dash is not forking, there will not be two chains, there will not be any such thing as "classic dash".  Indeed Dash's governance model enables any disagreements to be resolved quickly and peacefully, eliminating any likelihood of a Bitcoin Cash type fork in the future.  Dash is unified and will remain so.  The screenshot simply shows progress towards the next Dash upgrade and the first step on the Evolution roadmap.
