Oh ok.

I speculate Smash Tennis, Smash Volleyball, and Smash Tetherball.
Those would make good choices given with Sandbag Soccer.

I don't think that all of them will be sports based, but maybe we'll get jousting or some other events based of of other games.

Not all of them will, some of the mini games they add have to blend in with the Smash Bros. formula well. I don't think jousting works for Smash Bros.

Am I the only one that thinks that Sonic's sprites are too big?

No

Sonicc's sprites aren't big. Sonic's sprites ARE actually stretched, and he certainly needs a resprite.

3 vs 3 soccer arena would be great.

I speculate that the release date of SSF2β will be sometime around mid-to-late summer.

I assume that everything the devs want to cover isn't anywhere near finished right now.

I speculate that when the "final" version of the game comes out, there will be 6-8 immediate patches afterwords in the 8 months after release. 2-3 of those patches being major.

I speculate Stage Builder working this way:
-Same functions as Brawl, except you can choose between different styles of blocks regardless of the Background.
-You can use parts from the Individual Target Tests (Pipes, Steel Girders from the original Donkey Kong, temple-like Blocks from Zelda, etc)
-You can import your own Backgrounds into the game or choose among a few Backgrounds already in the game.
-You can import your own Music into the game or use the game's songs in the stages.
-Being able to export Stages to share with anyone.

I speculate that the new Game & Watch stage will be a Gallery series medley.

Are you refering to a music track or the stage itself?
Anyways, for a new Game & Watch stage, I speculate Flat Zone 3:
-Manhole: Pretty much like the Crusade counterpart, except that the bottom does not deal damage. It also works as the HUB
-Parachute: A boat that changes position as time goes on. Sometimes a Shark will jump and attack the players, but you can defeat it (much like the Chef in Flat Zone 2). The Palmtrees and the Helicopter serve as platforms. Of course, you can swim in the water.
-Fire Attack: Players fight in a Fort with Pass-trough platforms. Some Native Americans show up will throw torches attempting to burn the fort. Players can attack the torches but no the Americans. If a Torch hits the fort, the affected zone will start to burn. Altough, the fire works pretty much like Ness's PK Fire, or course all players are vulnerable.
-Ball: Pretty much the same as the original. Only a giant Game & Watch character that serves as a platform while moving its hands that, surprise surprise, serve as Platforms.

I speculate 3DS: Magicant. It's pretty universally agreed that that one would have benefitted from a hazard switch.

On the other hand, though, that would mean there'd be three Mother stages, so maybe not...

Other possible candidates are 3DS: Reset Bomb Forest, 3DS: Mute City, Wii U: Duck Hunt, and 3DS/Wii U: Boxing Ring.
