>  what do you think will happen to Alice? According to the web novels, she gained a ridiculously humanoid robot body to interact in the real world, so what will she do afterwards?

As far as I can recall, Alice actually returned to Underworld permanently. Her android body was used to showcase AI capabilities, however she chose to return to and remain in UW after that.

>  Is it possible they will tie into the main storyline in some way?

I'd guess that Girls' Ops, GGOA, and Clover's Regret are all canon in one way or another. They're separate enough that they don't conflict with anything from the main series, while being connected enough to allow for them to be canon to the SAO universe. That said, we don't know one way or another about them being canon.

>  Which one of them, aside from Kirito and the main cast, will make an appearance in the next arc? How much of a significant role will they take? How will they affect the stories in Accel World?

Honestly, I don't even want to guess at this. We know absolutely nothing about this next arc, and given how vague the teaser was it could easily be an arc about Star King Kirito.

>  And what of the original characters in the video games, such as Strea and Philia, Rain and Seven, Sumeragi and Premiere? Is it possible they will show up in the main series, even if only as cameos?

Highly doubtful given the nature of the games. That's not to say that this is impossible, just that I would be more than surprised if it happened.
