I was just wondering which sets would rotate out this fall for Modern. I'm building a deck and I don't want to get anything that is going to rotate out.

Modern is an Eternal format meaning that cards will never rotate out. Any card printed in 8th edition forward will forever be legal so long as they aren't banned.

Thanks I wasn't sure if it was just the sets from the last 6-7 years and they rotated or not. Thanks for the info.

I think they'll eventually change the name of that format, or tighten up the rules a bit on legal sets. After all, in another 20 years, 8th edition won't be very "modern", now will it?
