From HMI's viewpoint31 May 2018 23:38
I have been trying to put myself in co's place re next RNS. IMO Brian does not want to drop another until he has something definitive and tangible to contribute, like a major contract or unconditional MAPA - preferably both.
Anything less is likely to be interpreted as negative. "So he only stated this much meaning HMI still have the rest to do"
Therefore, if I am right, however long it takes, next RNS is likely to be significant and worth the wait.
