The streaming video wars just got a new player today in the form of Comcast’s new Xfinity Streampix.

Comcast announced this morning that its subscribers will be getting a new service this week that will allow them to stream content from its own NBC Universal division as well as Disney’s ABC, Sony Pictures and Warner Brothers.  Xfinity Streampix will be free to its “triple play” (television-Internet-phone) customers, or run $4.99 a month for anyone else with a Comcast account.

With a focus on older content, this seems targeted squarely at the Netflix Watch Instantly service which costs $7.99 a month.  The potential impact of this new competition is already being felt as shares of Netflix stock fell 3.65% today to $117.40.

The competitors seem to be coming out of the woodwork right now, with all of them putting Netflix squarely in their sights.  Earlier this month there was the announcement that Redbox is teaming up with Verizon for a streaming service, and now Comcast is following suit.  And let us not forget that Amazon Prime Instant Videos is also gaining some traction, and Hulu Plus continues to see growth as well.

While Xfinity Streampix is limited to Comcast subscribers, as the largest cable provider in the country, this could still have a significant impact on Netflix’s subscriber base.

Programming announced thus far for the service launching on Thursday includes 30 Rock, Grey’s Anatomy, Heroes, LostInspector Gadget, Strawberry Shortcake and The Suite Life of Zack & Cody.  As for movies, you can expect Analyze That, Brokeback Mountain and Crouching Tiger, Hidden Dragon among many others.
