There's no guarantee of this. The panel themselves will release a decision to the parties (so, not publicly) as soon as it's ready, I think. Basically, the longer the wait, the less there is an argument that the decision should be released at an opportune time (because this becomes more and more outweighed by the need to deliver a decision so that the process can move forward). And now that we've been waiting a while, I think it'll just be released as soon as it's ready.
The club and the PL might then cooperate on timing the release to coincide with a break in the football calendar, although I'm not convinced of this now. For a start, if the club have been substantially cleared, why wouldn't they want that out there ASAP? And anyway, once the parties have the verdict, it'll leak, one way or another. The parties hate each other so it's not clear that there'll be much desire to cooperate here in agreeing a delay to the release, it seems to me.
