Here's a little tip. Your statement was based entirely around what Pit's character would be like and how the game would fail because of what his character is like. His character has been in two canon games, neither of which you played, and a non-canon game, which you played, in which he had two spoken lines (his taunts) and was around for only an hour or two of the adventure mode. Call it speculation, call it opinion, but the fact is you haven't played either Kid Icarus game and are therefore missing a large part of how his character is portrayed.
You're right, though, that we don't know what the game will be like, but Pit's character has already been established in the Kid Icarus games. It isn't about speculation in this case.
