I'm well aware of the precedent and who normally gets the Tony for a Play Revival. That's why I said "Interestingly." I didn't make this up - I'm just repeating what the Administration Committee decided:
"Ohio State Murders will be considered eligible in the Best Revival of a Play category. Adrienne Kennedy will be considered eligible as author."
For whatever reason (presumably because she wasn't eligible for a Tony before for this play), if Ohio State Murders wins Best Revival, Adrienne Kennedy will share that award with the Producers.
(And to my points elsewhere on this thread - this is not the norm, thus is the reason they mention it explicitly. For all other revivals, the author(s) don't share the award.)
