Ya regreso / ya regresa
The Pimsleur course teaches this to mean "I'll be right back" / "He will be right back" and I have used it this way successfully and have been understood. However, I was surprised to see only a couple hundred hits on Google for this. Seems very common, is it not used very much?

In Mexico is much more common and informal "orita regreso"
That's how the future is commonly expressed in spanish. You use the present tense a lot more for the future. Ie: "te llamo mañana" = "I'll call you tomorrow." Ya is a useful little thing, it's used a lot where we wouldn't necesarily put "yet" or "already."
"Ya vengo"= "On the way," etc.
Yes, common (at least in Mexico) My husband watches sports in Spanish and when they break for a commercial they always put "ya regresamos..." on the screen.
