New Covent Garden Market - the procurement begins - is it premature?

I'm not too sure about the timing of the announcement, given that the Mayor's Nine Elm Plan has had its deadline response extended until the end of this month (and therefore, the consultation is still technically under way), but the FT is reporting that Jonas Deloitte are already working on the procurement of a development partner, starting this week.

I realise that the New Covent Garden already finished their consultation, so I am perhaps wrong in thinking that, whilst the Mayor's plan is still being consulted on, the NCG people are rather premature.  However, given the current comprehensive objections/suggestions that I know will arise from the Mayor's consultation, I'd have expected them to wait until all of the responses had been submitted. 

What happens if an objection to the Mayor's plan is significant enough to affect the NCG Market?  Wouldn't the developers need to be aware of that before they begin bidding?
