Wal-Mart continues to get very serious about making a play for gamers’ dollars this holiday season. The next move that will come next week will see the retailer sell the Nintendo Wii with a $50 gift card with every unit sold, which effectively brings the price down to $149. This deal will only run from December 5th to December 12th and is only limited to stock on hand, from our understanding.

If this isn’t enough, the retailer is also dropping the price of a variety of recently released titles by $10 from now till December 24th. Included titles are recent releases, including Uncharted 2, Halo 3: ODST, Left 4 Dead 2, Dragon Age, Batman Arkham Asylum, WWE 2010, Madden 2010, Tekken 6, MySims: Agents, Rock Band: Beatles, Lego Rock Band, and Mario & Sonic at the Winter Olympics.

The news that Wal-Mart would be moving to slash the prices of such recently released titles is certain to make a lot of competing retailers unhappy. The news from Wal-Mart has already impacted GameStop’s stock, with the company seeing almost a 9% loss in its stock price. It is also likely to impact retailers Best Buy and Target, as well.

No news has come from the competing retailers on how they will respond to this move by Wal-Mart, which amounts to slashing the regular retail price of these twenty-five recently released titles by 20%. Our sources suggest that GameStop will likely have no choice but to match the cuts on these titles, at least in stores that are in close proximity to Wal-Mart locations, if they don’t decide to just go ahead and slash the price on these titles at all of the company’s stores. As for chain retailers Best Buy and Target, it is expected that these titans will move to match Wal-Mart’s pricing.

One bright spot might be the fact that at least from what we are hearing, the move by Wal-Mart will be limited to stores in the U.S. only. While it could spread to Canadian Wal-Mart locations, as well, at least our sources don’t seem to think that this will be the case. The fight for video game dollars will continue on the run up to the holiday, and our sources suggest that depending on how sales go, we might have not seen the last of the price slashing yet.
