The porta-porta show with Raf, was extremely sympathetic.
The following show with Dr Peter Gill and a panel of interested parties also seemed designed to undermine the evidence used to convict, and indeed to call into question the notion of a "reversal of burden of proof".
This is important because it suggest not just a lack of legitimacy in the conviction, but in the judicial institution itself, much like the conviction of scientists for failing to predict an earthquake caused similar consternation, and was reversed (in large measure).
I think the state run Italian media is much more of a spokes tool for the government in Italy, then in other countries, due to its fascists history and traditions. It's much more like Russia, China, or North Korea - the way totalitarian regimes use the media. So I see coordination in these positive portrayals of innocence, throwing doubt on the legitimacy of the verdicts.
Also, I see signs that the political warfare between Burlesconi's party and the judiciary is also reached a resolution, and I believe this is the only reason Hellman's acquittal was overturned, the judiciary trying to avoid a politically motivated investigation of their members in relation to the case.
The hostilities are at an ebb, public opinion is being softened, I think the Judiciary wants this case flushed, while they can do so without having it used as a club against them.
The timing is right to ditch this albatross (not a reference to Monty Python), and I see it getting ditched. I see cassation canceling the conviction, without requiring a retrial.
As people say here, YMMV.
