Take-Two Interactive Software (TTWO) is tumbling after the video game maker announced that its Grand Theft Auto V video game would not be available to consumers until September 17. The game was originally supposed to be launched in Spring 2013. The company said it decided to delay the release in order to develop the game further. In a note to investors earlier today, Piper Jaffray analyst Michael Olson wrote that the delay should not have "an overly material impact on demand" for the game. No other major games are slated to be released in September, so Grand Theft Auto will have little or no direct competition during the month of its launch, according to Olson. Furthermore, the back to school shopping period should increase the buzz around Grand Theft Auto, the analyst wrote. The September launch also leaves the game better positioned to benefit from holiday sales, added Olson, who recommended that investors buy the stock on weakness today. In early afternoon trading, Take-Two sank 98c, or 7.50%, to $12.08. Meanwhile, video game retailer GameStop (GME) fell 78c, or 3.30%, to $22.86.
