When Take-Two Interactive launched GTA IV back in April, the game was an instant blockbuster, shattering entertainment records with $500 million in revenue during the first week. Now, however, the latest NPD data shows that the title has slipped to 46th place in August (down from 45th in July).

Dow Jones argues that GTA IV's "considerably" slowing sales could undercut Take-Two's position that Electronic Arts' buyout bid undervalues the company. The report also speculates that the slowing sales bring "fresh concerns that at about 8.5 million sold to date, Take-Two's powerhouse GTA IV may have a tough time meeting sales expectations." That said, a Take-Two spokeswoman said the publisher expects sales to "continue at an energetic pace."

With EA having recently let its hostile bid expire, Take-Two and EA have been talking behind closed doors. Analysts appear divided on whether or not a deal will get done. Some believe increasing the bid per share by just two to three dollars would cinch it, while others believe Take-Two's value is waning now with GTA fading, and EA won't increase its bid much, if at all.
