After months of disappointing sales, Nintendo's (OTC BB: NTDOY.PK) Wii is aiming to retain its spot as the top-selling console this holiday season. Nintendo announced today that it sold 550,000 consoles during the Thanksgiving week, beating out Sony's (NYSE:SNE) haul of 440,000 units.

Microsoft (NASDAQ:MSFT) didn't release sales figures, but its believed to have sold fewer units during Nintendo in November. Still, the sales figures represent a steep year-over-year drop for the company.

As CNET reports: "Nintendo put out a press release boasting that it had sold 550,000 Wiis in the U.S. during Thanksgiving week, leading Wedbush Morgan analyst Michael Pachter to estimate that the company may have sold about 1.1 million of the consoles for all of November. Last November, Nintendo moved 2.04 million Wiis."

Over the last year the company has seen its stock slip nearly 17% as the Wii's growth sputtered. That's a figure that not only badly trails more-diversified competitors Microsoft and Sony, but also struggling video game software developers like Activision Blizzard (NASDAQ:ATVI) and Electronic Arts (NASDAQ:ERTS).

Ouch. Maybe not an undeserved beating though. While game developers saw their drops mainly from consumers tightening belts, Nintendo faced a double-whammy of economic woes and increased competition from Microsoft and Sony aggressively slashing prices on their consoles; a strategy that lessened the Wii's advantage as the cheapest gaming system.
