I haven't heard anything about the PT investigation shutting up shop, so I don't see how any impending end to the current UK active phase would entitle PT to release information concerning the UK side.
AFAIK, the recent arguidos became so as a result of the UK investigation, quite possibly to comply with the UK notion of being interviewed under caution plus the right to a lawyer in an advisory capacity during the interviews if so desired.
On the PT side, the countdown to meet the strict deadlines is if there are either specific suspects or arguidos. (The two are not identical, although I can't find a clear definition of the difference - I presume it means that a "suspect" can be subject to covert surveillance prior to having arguido status.)
There were objections from the British to many of the files being burned to DVD for various reasons ... and I think in the main those objections were honoured.
Having seen how the sharing of information was abused first time round I think if Scotland Yard have any nous whatsoever they will have taken steps to ensure no such thing is repeated.
Even if Madeleine's case is is interrupted the files must remain confidential. An illustration why can be seen in Genette Tait's case where child serial killer Black would at long last have been charged and prosecuted. Only his untimely end prevented it.
Genette's had been a cold case for a long time and I rather imagine that had the case files been published there would have been no prospect of carrying out a prosecution at a later date.

http://www.bbc.co.uk/news/uk-england-devon-35961232In my opinion petitioning for information in what is a live investigation is an extraordinary course of action for anyone to come up with. It would seem millions are in agreement with that while only a couple of thousand think it appropriate to be told what is happening in a missing child investigation.
