While the first leak's claimed characters have all been confirmed as playable, the veracity of the subsequent leaks remains unclear. While the second leak accurately slated Palutena as playable, she was a character widely expected to be playable, due to Sakurai having worked on Kid Icarus: Uprising and the presence of the "leaked" images that had been posted on multiple news sites. Additionally, while "Pokémon from Pokémon X and Y" was technically correct, the leaker's inability to specifically state Greninja and only being able to do so with a vague blanket statement was scrutinised. The leaker also never implicated Rosalina as being playable, and has never implicated anything outside newcomers that was later confirmed as correct, bringing doubt into the extent of the leaker's inside knowledge. The prevailing theories are that the leaker had legitimate information for the first leak, but made up predictions for the subsequent leaks, or the leaker had significantly outdated information. The latter is supported by the fact he could only refer to Greninja as "Pokémon from Pokémon X and Y", when Sakurai confirmed that he decided on Greninja well before the release of Pokémon X and Y (which was six months before the second leak and the Smash Direct), and the fact that only three of the original six were revealed at E3 2013, when the leaker initially said all of them would be. The leaker also just only brought up the Ness vs. Lucas debate at E3 2014 with a non-definitive answer about it, with it being highly unlikely that the roster wasn't finalised well before this, as the final few months of game development are typically devoted to balance tweaks and debugging.
