I agree with your predictions for the most part.

I think the Roy and Ryu amiibos will be announced, and a possible allusion to the development of the Cloud ammibo.

Then, I think (and hope) that Great Bay from Melee will be announced to return to Smash 4 as a Smash 3DS exclusive. Even if it isn't exclusive I'll be happy with it, but I feel like the Wii U people get all the good stuff (I want Pirate Ship) :(

I think another stage will be announced as well, either a bundle stage with one of the newcomers or a Smash 64 stage, most likely Saffron City.

Then two other characters will be announced. I think it will be either Inklings, Wolf's return, Shovel Knight, or Bandana Dee *fingers crossed*

Sakurai will go into an in-depth look at each of the characters, much like he did with Roy and Ryu. Then the presentation will end with the announcement of a new game mode? I'm a bit iffy on this last prediction, but stay hopeful nonetheless.
