I agree this seems different from Calciopoli, mainly because the procedures seem to be legit/legal, and objective evidence may have been found.
I don't think it will end up with Juve's relegation, also because there doesn't seem to be political willingness for that - Juve is no longer dominating, and I think FIGC has learnt its lesson that destroying Juve = destroying Italian football.
BUT I would recommend caution. As a reminder, the punishment from Calciopoli, if I'm not wrong, was also kind of "made up" - it wasn't positively expressed in the rules. So the fact there's no express rule stating sportive sanctions due to these infractions shouldn't make it definite that a harsh sporting punishment like relegation won't happen. It definitely isn't out of the cards. This is Italy, after all.
If this happened 4 or 5 years ago, I could actually see a bigger danger of relegation.
Anyway, this is a fucking tragedy. Agnelli is the father of it all. Let's see if this collective resignment will actually save the club from anything.
