There's never a dull week on Wall Street. Let's go over some of the news that will shape the week to come.

The new trading week kicks off with Yum! Brands (NYSE:YUM) reporting fresh financials. The parent company of Taco Bell, KFC, and Pizza Hut has run into some hiccups in China lately, and that's a bigger part of the company's business than you probably think.

Maybe those Cool Ranch Doritos tacos -- they're coming soon, you know -- can save the day.

Infinera (NASDAQ:INFN) is one of the many companies reporting on Tuesday. Analysts see the digital optical networking specialist posting a quarterly loss of $0.06 a share, matching the deficit it served up a year earlier.

LeapFrog Enterprises (NYSE:LF.DL) hops up on Wednesday. The maker of electronic learning toys appears to have had a great holiday season. NPD Group's Retail Tracking Service, in ranking the best-selling toys of 2012, finds LeapFrog claiming three of the top four spots with its LeapPad Explorer, LeapPad2 tablet, and Explorer licensed software. Naturally, investors will want to see how all of this success translates into financial results, and that's what Wednesday will be all about.

Activision Blizzard
(NASDAQ: ATVI) comes to play on Thursday. The country's largest video-game maker reports at a relevant time. The industry has been sliding for the past three years, and a few companies had disappointing news for investors earlier this week.

It will also be interesting to see how the company's Call of Duty franchise is holding up, given the recent political scrutiny over violent video games.

Friday is usually quiet on the earnings front, but that won't stop Brookfield Infrastructure Partners (NYSE:BIP) from reporting. There are plenty of master limited partnerships out there yielding more than Brookfield's 4% these days, but the company's diversified investments in infrastructure -- from electricity to timber -- make it a well-rounded play for income investors.
