its not likely that they do, though. For one, all of the tomes shown were the second level except Thunder, and for two, it wouldn't make sense for a character to have four chargable B moves. As much as i'd like to hear him yell "bologna!" every time i used his side-b, i doubt it
So Chrom wasn't added because he would have been just another swordsman, while Lucina reeks of Marth clone. I get that Lucina being ever-so-slightly different from Marth is strictly better than having her be an alternate costume, but this is silly.
Kinda strange reasoning. He decided not to add Chrom so as to avoid having yet another Fire Emblem sword-wielder, but Lucina got it because she was only a little different than Marth and got upgraded from costume to full-on character. She's not replacing or stealing anyone's spot so ultimately it really doesn't matter though. I was hoping that she would at least have some different attacks and a bit more variability in some attributes (attack speed, recovery, jump, etc).

It's obvious why. Lucina is just a skin with slightly different hitbox properties, something that could be finished in not even a week. Chrom would've been a completely new character, meaning that they would have to create a new model, design a brand new moveset, and constantly playtest and tweak him to make sure that he's balanced with the rest of the cast. And considering that only half of the confirmed cast is ready to be presented after two years in development, it's safe to say that it would take much longer.
Game and Watch's status is kinda confusing - it would've been really easy to confirm him after Pac-Man's Trailer, and the fact that he hasn't been yet is disconcerting. Jigglypuff, Ness, Wario, Ganondorf and Meta Knight all seem like given veterans.
I think Sakurai made a mistake with the G&W in Pacman's trailer, because now a bunch of people already consider him confirmed, a bunch have no idea, and even more have various different views on the matter. I kinda thing G&W is just going to be quietly ignored until its time for a full roster reveal, or just when the game comes out and people unlock/see him.
If Game & Watch isn't in, then Sakurai might as well eat an entire Gameboy and shit it out on Gunpei Yokoi's grave. There's no way they'd cut the first handheld character from the first handheld Smash Bros.
I think it helps to rationalize the Lucina/Chrom thing by thinking of it this way: Lucina was going to be in anyway. She's extremely popular in Japan AND her in-game story of pretending to be Marth means they can make her an easy clone with little work. What Sakurai was debating was between Chrom and Robin, and I think we can all agree that Robin is a 10000x better choice because of his unique moveset and playstyle. It would be hard to make another generic blue-haired swordsman have an interesting moveset what with so many swordwielders, and making him a clone of Ike or Marth would have just been bad.
