Of course we won't know for sure until we get the formal verdict but let's imagine a scenario in the hearing where the Mancini Al-Jazira contract is being discussed.
Apparently Mancini wasn't called as a witness (which might or might not tell us something about the strength of the PL's case). It's up to the PL to make their case, not for us to make ours, but let's say that the PL did produce some evidence indicating that the contract was (in their view) a sham, but we were able to show irrefutably that Mancini (or his representatives) fulfilled the terms of that contract completely. We'd be pretty confident we'd won that argument
Or the Fordham payments, where we could refute the PL charges and show that the payments had been properly declared to UEFA under FFP reporting, and that even if we'd paid them directly, there would have been no impact on PSR/FFP. It might be we'd get a slap on the wrist for slightly underdeclaring expenses possibly. However we also know that Fordham wasn't a deliberate attempt to hide expenses, but to generate revenue in the 2013 financial year. We could also show that UEFA knew about these payments by 2015, but no charges followed. Of course the PL panel would be free to make up it's own mind but, again, the PL would need to make their case on the balance of probabilities. And even that most cautious of commentators, Stefan, doesn't think they'll be able to do this.
So yes, we won't "know the outcome" but we should have a reasonable idea.
