I agree. I see no rationale for BP to remain idle if there's serious interest. You want the asset under your control as soon as possible, unless there are some prerequisites needing buttoning down, i.e. Flashworks perhaps, certainly at least an approval. With that said, paperwork should be in place awaiting for the key milestone(s) to occur. Beyond that, I don't find a reasonable argument for BP and NWBO to diddle daddle for some time horizon to come and go. BP's are way too big and accountable to their stakeholders to be in the business of toe dipping, assuming they've seen what they want which validates the target acquisition.
