TS4 hints at "unexpected" expansion packs coming in 2020

Guys. I just thought of the best idea! What if they did Sims Garage band? And we had more musical instruments to choose from! Drums? Saxophone? Am I right? Dang that would be really cool! We could collaborate music with other sims who love music, perform on the streets of the city? Attend concerts! Get awards, and participate in music festivals, and become a Celeb of course. I made the Spice Girls on my game once. haha This would be so much cooler.
