Sims 4 news from EA: pack download nos., game future

Well in the EA statement it says Expansions. I'll take that at face value. Some won't. 30 million EP's is no small cheese no matter if it's bought on sale or not.
Some didn't believe the 5 million pin thing from 2 years ago and that was confirmed later.
Does anyone remember if it was actually said that Seasons or Pets was the biggest seller? Or was that speculation too? I'm wondering. Would love to know what EP's most people have for curiosities sake.
