Hi Tony,
Welcome to the community! Sorry no one has responded until now.
You've probably already discovered that there is a Latin Percussion EZX available that works with both EZD and Superior Drummer. As of right now, that's the only Toontrack option for you. I have that EZX, and personally, I find it to be pretty underwhelming, to be honest. But it may suit some of your needs just fine. Who knows?
There has been a bit of talk in the past about doing a more extensive percussion set, and I believe it was around a year ago that TT said there was something in the works. But that was a year ago, so who knows what the current plan is.
