I seem to remember that either it was at the December 18, 2010 hearing or the January 22, 2011 hearing (maybe both) that it was requested by the prosecution to include all evidence from the Guede case file to the current appeal trial. I believe the request was granted by Hellmann.
Frank from Perugia-Shock mentions this request of the prosecution in his post of December 18, 2010.

I will see if there is mention of this request by the prosecution in the Italian media. I believe there was but cannot remember where.
What impact this will or will not have on the current appeal I cannot say, other than I believe the defense in their appeal are not wedded to the lone wolf theory of the murder. And I do not think the appeal court is bound by the decision of the high court.
To another subject - PMF has acquired the Guede Motivations. I am perusing the report. It is interesting but I have not found the part yet where the November 17 "I was there" intercepted call is written.
