Why haven't JYP spoiled NMIXX's comeback yet?

maybe they thought it's probably not a good idea to spoil a comeback song

They did a great job, because the Sneakers fiasco still haunt me

Maybe this is for the best though

I expected a snippet already but still nothing, I'm surprised by Jyp being secretive with their comeback

Smart move. Who even releases snippets 3-4 weeks before release? Only JYP.
