Right, so the logical possibility, IF there really are lawyers who are disallowing release of the PRs, is that the PRs must not be verifiable or fully valid yet. Right?
If the info contained was material and/or valid, then there's no reason they can't release it.
How's this for another possibility... the lawyers (trustees?) are TELLING them not to release the PRs. Hence, more inside loading, etc, but there's no LEGAL gag on PV or SS. Which means the PRs should either be released, or STFU and stop talking about them. The situation is unethical either way you look at it. Maybe it's just a "don't release anything now" type of situation, so that their own interests can be furthered first before that of shareholders? That could actually be a positive view on this, but I'm not sure it warrants too many positives right now.
