directors staying quiet

With regard to Gaga's recent posting about the UK broker report: It occurs to me that the VTI Director's silence about the latest gilt edge results (Virotec's solution is the only one still going strong out of all tested - ie - winner) is a break from their well-established pattern of making big announcements about things other than concrete $ contracts. They're being very subtle about this. This may indicate that they see the action coming through in the near future, and they don't want to inflate the share price in the short term with more news. Any opinions?
