Why no announcement from ARV?

Possible reasons (in no order) are:

1. NOVO have released the information - so its is public and ARV has no obligation under ASX as it believes that ALL 'information that can materially impact the share price' has been made public AND that shareholders are aware of this. (granted this is a bit thin)

2. They are conducting their own analysis of the samples at a different lab and are yet to receive the results.

3. They are also doing COBALT assays that NOVO did not do and thus are waiting for those to have complete assay results.

Can anyone else contribute/add to these?....
