Of course, Retaliation was initially set for release back on June 29 before Paramount Pictures would make a risky (and costly) choice to nix those plans, opting to shelf the film for nearly a year for a complete 3D conversion and possible tweaks to the film itself.
Well, after several months off the radar, it appears that the Retaliation hype machine has reactivated as its announced March 29, 2013 release date looms closer. (Although, the poster says March 27.)
The initial promotional period for the film seemed to downplay Tatum's involvement in the film, leading to speculation that his Duke character, the central hero in 2009's G.I. Joe: The Rise of Cobra, would be destined for a bad ending early on in the sequel, serving only to pass the hero baton to Roadblock.
However, Tatum's star has risen considerably since the delay (and according to People, he is 2012's "sexiest man alive,") so, it is entirely possible that the delay may have provided a way to keep the Duke character on life support to possibly renegotiate a larger role for Tatum in a potential third film. -- That's just speculation, though.
