Rating the smash direct an 8.
It delivered on the launch windows (although I'd have preferred an earlier Wii U date), 5 new characters, showing off tonnes of info about everything, loving the look of online, new game mode in 3DS, brief showing of custom movesets, and customary Sakurai trolling.
Only 2 misses from my perspective: I wanted to know about the singleplayer modes, and more brand new characters.
Yes, 5 reveals is awesome, and I genuinely love that Sheik and ZSS are proper characters now. Greninja looks awesome (and you gotta love how he originally looked like Mewtwo, that Sakurai is one troll bastard). But I kinda wanted to see Lucina, or Shulk, or Palutena; someone a bit more left field.
Still a good direct though (although not as good as the W101 Direct) and I'm looking forward to watching it again tonight.
