Activision closed on its transaction with Vivendi Games Thursday and officially became Activision Blizzard (NASDAQ: ATVID), according to an article at SmartMoney.com. And I am pretty excited at the prospects for the new business (I am a shareholder). It's going to be a tough competitor against Electronic Arts (NASDAQ: ERTS) and Take-Two Interactive (NASDAQ: TTWO). (Of course, the latter two might merge at some point.)

Activision is riding high with its Guitar Hero franchise, and Vivendi Games brings an incredible asset to the table in the form of online gaming sensation World of Warcraft. I can't say I know much about World of Warcraft the game itself, but I know it has a huge following. What else do I need to know, right? For 2009, management at Activision Blizzard expects pro-forma operating income of over $1 billion and perhaps $1.20 or more in terms of earnings per share. That puts the stock, which rose over 5% on Thursday and closed with a price of $31.77 per share, with a P/E ratio a little over 26. That isn't too bad a valuation considering the growth potential. And when the holiday season comes around, I'm sure people will still be buying the publisher's software for gifts, recession or not. Whether it's the Sony (NYSE: SNE) PlayStation 3, the Microsoft (NASDAQ: MSFT) Xbox 360, or the Nintendo (OTC: NTDOY) Wii, gamers will be buying the company's products for these platforms in droves.

The stock has retreated from the highs it reached back in June when I wrote about it, but I am still bullish on the thesis here. Activision Blizzard should do really well, but with the markets in turmoil, you can probably wait for a pullback before buying.

Disclosure: I own Activision Blizzard; positions can change at any time.
