Yeeeeah, so....I'm just gonna go ahead and speculate a bigger Hueco Mundo (might've speculated that yesterday, I don't remember) and a bigger Green Hill Zone. I mean remember how big and spacey and fun it was on Brawl? With those huge gaps of explosions on the stage? Yeah, that was pretty cool. Obviously,it would be nice to see background characters in the stage too. Maybe Cream and Cheese or Emerl or even Blaze the cat. But my main speculations are first, that MKII will have all the different Bros (Hammer, Fire, Boomerang, Sumo, and Sledge) from the Super Mario series, mystery boxes for items, and music boxes that could occasionally bring out Starmans like in Super Mario Bros 3. If I could see all that, I would totally flip! But hey, even if the bros aren't in the stage, I feel like they could be deserving of a spot as Assist Trophies. Also gonna speculate options for custom revival platforms and blurs for normal attacks to come back. Those kept the game pretty unique and neat looking to me. I kinda feel like the Sound Test may or should be in a future patch. No harm in having it. One more thing. Hopefully, Mario's back jump (initial jump) will have a faster animation. Oh...and really hoping a more detailed background for Fourside. Aaaaaand...gonna speculate Team Chaotix from Sonic and Knuckle Joe from Kirby as Assist Trophies. Hopefully though, Joe appears as playable.

I speculate that the Final smash flame will also get a 3d upgrade.

I speculate new items in the next version.

Wait, do you mean a new look possibly being flash animated? I'm pretty sure nothing in this game is 3D. Well at least that's what the devs said. Everything in this game is just 2D. Certain things just look very detailed. Not completely up to the point of looking 3D though.

With 3D i mean that the sprite will be replaced with a higher quality flame like Goku's kamehameha

The game actually does have a few 3D elements

As in the "Mode 7" effect for Hylian Skies?

I speculate Pokemon Stadium 3 will have a "overlay" on the stage sprite and get a camera feed on the background television.

That's probably the most obvious one, the rest are very subtle.

I speculate that if by some chance Luffy gets in, he'll be tied to Gangplank Galleon rather than getting his own stage, like how in Melee Marth and Roy got Fountain of Dreams and Temple, respectively.

Final Form mode will be added to Special Versus, next to Invisible.
Stamina will be an option similar to time limit and stocks in the rule list.

I think that Stamina should be made into an option like time limit/stocks. Maybe once you reach 0 HP that means a lost stock.

final destination form stages?

720p and 1080p mode.
It will happen.

At the very least 5 Target Test stages
Actual Recolors maybe?
More everything.

Not sure if resizing the Flash Player (other then manually by yourself or using full-screen inside Flash) is either possible or practical. With GPU acceleration especially, I don't see a reason for that, but who knows.

5 Target Test stages seems inevitable. Since they seem to be going with Brawl's route of Target Smash (which, IMO, I like better then Melee's a bit), five based on difficulty seems the most likely.

Hopefully they'll come up with something that won't make the game lag and won't be a burden to implement since pixel manipulation can be problematic in Flash to program effectively. I'd give it time before we see that happen but I have faith in the devs.

And "More everything" will happen since were still in demo status.

Run the game on Fullscreen: Quality and on High. Boom.
