My thoughts exactly. Although I really think the entire reveal process has just been bad for this game. For example, when the game was revealed, a Jak stage was shown revealing his presence in the game. (as well as any surprises about his inclusion) This could have been avoided by showing Parappa's stage instead because Parappa had already been introduced as a character. That way we would have gotten a nice surprise when Jak would be unveiled. (it also could have worked in reverse with Jak being unveiled with his stage, and Parappa saved for later)
To give it a Smash analogy, say Smash 64 was shown for the first time. Mario, Kirby, Link, and Pikachu are all debuted, along with a Mario and Metroid stage. Now everyone has just been practically told that Samus is in the game, but instead of revealing her, the next reveals are Yoshi and Fox. Fans are now waiting for Samus to finally debut, meanwhile Nintendo continues to reveal unexpected characters that could have been saved for later. In addition, they could have kept Samus herself a secret by showing say a Pokemon stage instead when the game was revealed thus keeping surprises in store.
