We know, we know—it's only September. When it comes to toys, though, it's never too early to start thinking about the holiday season, especially for retailers. It is big business. Huge business. The buying frenzy of the holidays can comprise 40 percent of the total annual profit for a toy store. With this in mind, Toys R Us has released their 2012 Holiday Hot Toy List to get a head start on the hottest items this year.

So what's on it this year?

The list includes kid-friendly tablet devices, like Toys R Us's Tabeo, collectible dolls of the incredibly popular boy band One Direction, and old-school favorites that some young parents might remember from when they were kids. The toys on the list, some of which can only be found at Toys R Us, cover the whole toy spectrum, from established hits to items from more obscure manufacturers.

According to Lisa Harnisch, the general merchandising manager for Toys R Us, the company has "an incredibly skilled team of merchants here that track new products and identify toys." Finding that next big hit is something that everyone wants to be able to target early.

Toys R Us is also implementing a reservation system that will allow customers to set aside any of the 50 toys on the full list. The program will run through the end of October, so if you're a parent who likes to shop ahead, be sure to stay on top of that. Once November rolls around, all bets are off.
