Yes, we are preparing a mass mailing on this topic. If BitShares X Test is successful we will simply drop the Test from the name, if it fails in some manner that is unrecoverable then a new snapshot will be used. Thus the value of the BTS (and BitUSD etc) in the test chain must factor in probability of catastrophic failure and reset of the chain. It should go up over time as the likelihood of failure decreases.
This process of launching test networks that "might be final release" networks will continue until all bugs are found. This is necessary because for a test network to function it must have a non-0 value otherwise bitasset evaluation results in divide by 0 errors.
Note that having many parallel chains was always in the plan and a version 2 chain with variable interest rates set by market forces will come out later as well. So some bugs that result in the launch of a new chain may not mean the complete death of the initial test chain. If the initial test chain has any residual value or can be 'patched' then it might take on a life of its own.
没有人知道明天这些 bts 会是什么样的价值，可能一文不值，可能价值不菲。
