I was with a Korean friend ( Ms Joo)and we were waiting for our another Korean friend(Ms lee), I asked Ms Joo " Where is Ms Lee? ", she answered, "coming anytime" I told her that the better way of sayin' it is " She's coming any minute now" and then I told her she could also say " She's coming in an hour, in two hours,etc" but after an hour I realized that I should have said " She'll be here any minute now/in an hour /in two hours etc"...but i didn't have any chance of changing it, Is there a difference? Is "she's coming wrong in that sentence?"
The most correct response would've been, "She'll be here any minute now." "She's coming any minute" is not technically correct, but it does express the idea so that it would be understood by a native speaker.
