Please note that this post is pure speculation and is not based on any official announcement / statement by EA about TS4 Pets!
The Voice Actors behind Interactive Video Games / SAG-AFTRA are currently on a strike against many video gaming companies, including Electronic Arts, Activision, WB Games and more!
The strike comes in light of an unsuccessful 19 months of negotiations after the existing labor contract known as the Interactive Media Agreement expired in late 2014. Overall, the strike is an effort to provide more secondary compensation along with other concerns, such as transparency upon hiring talent and on-set safety precautions. Any title that went into production after February 17, 2015 will no longer be supported/worked on by voice actors until their needs are satisfied.
The SAG-AFTRA published a list of all affected video games. Some of the titles have yet to be announced, some have been released and some are hiding under a certain code-name. For example, they have listed Hockey ’18 (NHL 18) which has yet to be announced by EA. One particular title that struck out was ”PETS”.
In case you don’t know (but I highly doubt that), PETS was the title of pet-themed Expansion Packs for both The Sims 2 and The Sims 3! There is no other Electronic Arts title that focused on Pets other than The Sims 2 Pets and The Sims 3 Pets, so this listing proves that there is a high possibility that The Sims 4 Pets is in production!
In case you missed, SimGuruDaniel replied a few weeks ago to a Reddit post asking if TS4 will ever get Pets and Seasons, saying:
