Video games are Walmart's new front in the price wars

It looks like Walmart is fixing to do for video games what it's already done for toys and books this season.

Wal-Mart Stores (WMT) announced it has cut the prices of popular video games like Halo 3: ODST; Rock Band: Beatles; and Left 4 Dead 2 by up to 20% and will give away a $50 gift card with each $199 Nintendo Wii console sold Dec. 5-12. It's not exactly a $10 toy or $9 book, but as the retail behemoth's announcement said, it's "game on."
