(CNN) - The holiday season is always make-or-break for the toy industry, and tracking down the hottest items can be pivotal for anxious parents and eager children.

The toy industry in the United States is worth about $22 billion for traditional toys, and it's expected that a mix of high-tech and old-school nostalgia will top the wish lists of children in 2013.

A retro theme to this year's hottest items includes characters like Elmo and classic Disney princesses. Meanwhile, a newer generation of princesses hits on another hot trend - interactivity.

Beyond the dolls and games, kids want to do what grownups do all the time - swipe away at tablets and smartphones.

"Two-year-olds now are swiping before they're speaking, so it's hard not to get excited about the 'wow' that we're finding in our toys, devices and learning toys," Laurie Schacht from The Toy Insider said.

If there's a must-have item this holiday season, though, it probably will not reveal itself until after the big shopping weekend.

That's why experts say that if something catches your eye, buy it, because you don't know if you'll find it again.
