I generally hold a pretty low opinion of Square and their mishandling of the Chrono series as well.
However, the mobile game Final Fantasy Brave Exvius is currently having a Secret of Mana event where you can get characters from that game for your team. This is the first time FFBE has introduced characters from a non-Final Fantasy title, and it opens the door for them to do the same with Chrono Trigger characters.
So what? Assuming they even do that, it's just a glorified cameo appearance in an unrelated game.
Although it's totally playable without spending a dime, FFBE is microtransaction-driven game. One of the things you can spend money on is summoning more characters. They're randomly chosen, of course, to keep you buying until you get the one you're really after. I suspect Square may be using these events as a barometer for what people want to see—if sales skyrocket during the Secret of Mana event, they'll know there's interest in the series. The fact that they're reaching so far back into their library seems to suggest they are indeed trying to cash in on nostalgia.
It's a long shot, but hopefully they'll do a Chrono Trigger event which earns a zillion dollars, and Square will have unequivocal proof that the series is worth reviving.
