A port/multiplatform announcement at E3 is not a Megaton.

Valkyria, you can't be serious. "Megaton" announcements are about people's reactions to them, and nothing else. FFXIII on the 360 was one of the biggest megatons in years, and that it would be topped by pretty much any kind of "surprise" this year borders on the absurd.

Granted, a Zelda game would be a megaton, in all likelihood, but that's only because people would react to it that way. MGS4 on the 360 might be a megaton - FFvXIII might too. It depends on how people react.

 

then wii music was a megaton ! =P
