The charges from 2018 onwards are for failure to co-operate - i.e. the PL suspects there is stuff they should charge them with, but as City haven't provided the requested information the PL cannot determine whether they should be charged, and if so, what those charges should be. THat's all that should be read into the lack of specific charges from post 2018 - the PL suspect, but they don't know. And they don't need to charge them, protectively, with anything and everything they could be guilty of because there is no time-bar on when they have to bring those charges.
My take on this is that if City are found bang to rights on the earlier years, then whether there are any specific charges for 2018 onwards will depend on the severity of the punishment for the earlier years. If the panel relegates them and strips them of titles then there's an argument that there is no need for any further action / punishment (and indeed, how could it get much worse for them anyway?). Think Simpsons "Stop, he's already dead" meme. In truth, the effort to bring those charges versus the additional punishment is probably not worth it. But I would expect them to put City into an enhanced monitoring process for at least 5 PL seasons, kind of a financial equivalent of release under licence - any funny business and you're back behind bars lads.
However, if they are found guilty on some grounds and handed down middling punishments then I think the PL will (be forced to) have another go as the other clubs in the league are unlikely to find the outcome satisfactory, especially if they believe City are continuing to break the rules and / or are benefiting from a legacy of cheating.
If they get off scot-free and / or on technicalities (or it's found that the charges are "not proven") then I think that will be the end to it, bar decades of acrimony from the other clubs. If it's a "technicality" ruling then I wouldn't be surprised to see some form of financial settlement to ward off the risk of other clubs suing, especially those denied titles or European football.
And I do share the view that the PL would probably regard a not-guilty / not-proven verdict as a best possible outcome - they can say they tried and it's not their fault. It would be tempting for them to try, but not to try quite hard enough, to get a judgment against City. The problem they have with trying to stage such an outcome is the precedent of the UEFA hearing - they weighed the evidence and found City guilty. And bear in mind that 5 of the 115 charges are for breaking UEFA's rules - it's arguable that those charges are de facto found against City already since UEFA already ruled against them and only lost the appeal on technicalities that don't apply under the PL's rules - the CAS ruling doesn't hold that City didn't break the rules, just that UEFA left it too late to charge them. If the Premier League fails to get a guilty verdict on those charges then they will look like total chumps given the prior UEFA ruling. And finally, in the recent PSR hearings, they have really gone after the clubs they charged - I think it will be obvious if they don't try hard enough against City.
I personally think they should be made to change their name to "115 FC" or include "115: in their club crest for all eternity and every one who defended them should be made to have "115" tattooed either on their foreheads or somewhere intimate and very painful.
