The week seems really lame primarily because of the leaks, but even without the leaks it'd still have been boring. None of the info is truly new, it's just visual representations of things we've sorta seen or knew about already, officially.
I'm assuming Sakurai's just getting this stuff out of the way, and then pulling out some last minute excitement via a video or direct right before Japanese release.
Honestly, people shouldn't be expecting characters or stages from this point on.
With the leak in mind, we have 24 out of 34 (or 35?) stages. I'm assuming some or all of the remaining 10 are secret.
And the ONLY character we'll probably get (if any) is Wario, to finish off the starting roster. This would give us around 33-35 starters (Since Luigi, Lucina, and the 3rd parties may/may not be secret, but special cases) and 14-16 secret characters. This is ignoring Mii Fighters & if this is not the full roster.
I mean, I honestly think this is about it for big reveals until a complete leak and/or a Direct/Video.
We know all the modes, officially (but haven't seen All-Star, but we know how it may work unofficially).
We know all the side things like Customization, Trophies, Challenges, Music, etc.
We've seen a lot of the menus. We know most, if not all of the attacks via the site or Famitsu.
The only thing we don't really know is the Final Smashes for Peach, Diddy, Dedede & Lucina and what that weird minigame is with the top-down view of tops spinning at each other.
So all that is really left, before shifting gears to Wii U news is that stuff, more trophies, more Assists/Pokemon, clarifying a few items we've already seen, more menus we haven't seen yet and if Sakurai wants to show off costumes.
