It has been officially announced that there is planned dlc for the game. The first of which will be free and includes four pieces of dlc, two weapons and two multiplayer stages.
According to the author of the article: "The release of the Falcon’s Talons weapon will be coming April 3rd alongside the Submarine stage. The Eclipse Scythe will slice its way into the game on April 17th with the Desert Stage."
Strip those weapons away that were originally on NG2, and make them DLC. Fearing the backlash of DLC controversy, they quietly ditch plan A and went with plan B which is to make those FREE. As a result of making it free, they hope to come off as the "good guys" rewarding their loyal fans.
Ho ho ho ohhh Tecmo... who are you trying to fool?
Then again, I'm probably just making this all up.
Nice try Tecmo don't be like Capcom.
