I've got a slightly half-glass full attitude to this wait.
If the news is bad - (ie- 1% poor grade), they don't need to dot their "t's and "i"s to the same degree. If it's bad - its obviously bad, no need to over-analyze - they'd just announce it as soon as they know, as they are obliged to do.
But the longer the wait of analysis of RH_C8 - the more likely it is good news, as I think they will make sure the testing and results are above reproach, and there is only flawless data in a good-news announcement (got to deal with Poet).
