The artificial sweetener in Diet Pepsi is about to change, but fans of the old formula may still be able to get it.

PepsiCo said earlier this year it would replace the aspartame in Diet Pepsi with sucralose, another artificial sweetener many know as Splenda, in response to customer feedback. That change is set to take place in the U.S. starting this summer.

But during a call to discuss its earnings Thursday, PepsiCo CEO Indra Nooyi said “for those consumers who still love Diet Pepsi with aspartame, we’ll figure out how to make it available online.”

A representative for PepsiCo declined to elaborate on Nooyi’s comment.

According to industry tracker Beverage Digest, Diet Pepsi was the seventh-most-popular soda in the U.S. last year, with Diet Coke coming in third.
