At the risk of furthering Grinchgate, let me take my herbal supplements fortified with horse manure and put my Alex Jones hat on for a moment:
It's very possible the Grinch leak revealed all the DLC. As I've said, I thought the insiders must have reliable info that it was fake to be so quiet even though I thought they should have talked more openly, even if obliquely, about it. Turns out they did have solid data, but I've also said that i think Nintendo is running a Marvel Studios-esque smokescreen campaign when it comes to leaks (and did you see Thanos Hand in the trailer--I mean, that was a Final Dustination; Sakurai's obviously been watching the MCU).
Given that I find the Grinch leak so ridiculously elaborate that it's hard to believe it's fake, here's what I will call CC Theory for y'all's future reference.
Grinch leak is real. It is Fighter Pass. Shadow and Isaac are assist trophies AND fighters. That is the simple smokescreen Nintendo put out to confuse the data. If it leaks both ways, nobody knows who to believe. Those assist trophies will probably just not appear when someone is controlling Isaac or Shadow.
The Ken art looks very close on the Smash site and the banner. Omni: professional analysis please? The color looks off and maybe how the fire wraps around his arm, but the pose is nearly identical. Perhaps the result of a work in progress? After all, Fighter Pass is still a ways out from reveal.
If Grinch leak is real, Vergeben was right about everything, including the potential Microsoft rep and Square rep. After all, we have Geno and Banjo in the grinch banner.
Further supporting that, the other reliable source, Gaming Intel has potentially scooped an N64 Classic imminent announcement and that it will have Banjo Kazooie on it. Maybe the Banjo DLC will tie to the release as a cross promotional event.
Before you tell me the numbers don't add up because there are six unrevealed characters in the grinch leak and five in the Fighter Pass. Aha, well Sakurai said Smash Pass is for non-echoes. Presuming I'm right about Shadow being a dual character and assist, let's say he came in as a Sonic Echo. Maybe Echoes will be like Piranha Plant and not considered part of the Fighter Pass. If Shadow is indeed an echo, he wouldn't be part of Fighter Pass per Sakurai. By that logic, Geno, Isaac, Banjo, Mach Rider, and Chorus Kids are unique fighters to be available via Fighter Pass.
There is no retro rep. Why? We've had a retro rep every Smash except this one. I suppose you could argue that Piranha Plant or Ridley fit the bill, maybe Simon, but I mean a retro rep that has been dug out of obscurity and revived. We got our 3p rep--Simon, our fan favorite--Ridley and K. Rool, our WTF character--Piranha Plant. Where is the retro rep? Mach Rider.
To quote the philosopher Chanondorf: Suck my blank. Grinch Leak isn't dead yet.
