I suspect he's been advised not to speak yet (whether by Kenwright or someone else). We have had so many PR disasters around the stadium issue that if he speaks too early and his plans don't immediately some to fruition it would be seen as another KD/DK/WHP fiasco.
I get the point around wanting to hear something now but I would rather the statement wasn't misleading or half baked.
Come on. I don't think he has made it to here in life by needing to take advice from Kenwright on when to make a public statement. I think he has a good handle on how to conduct himself in a light that he wants to paint himself in.
