I think they'd probably be teleported to Japan cause that's the only way I can see Dawn getting there or perhaps Willow opens up a portal as we've seen she can do that now. But I'd also like to see someone that can challenge Willow cause right now it does seem like Willow is virtually a goddess. I mean is Twillight more powerful than her? Will it eventually be a battle between Twillight and Willow instead of Buffy and Willow. (Since they can both fly kind of like the final battle in the Matrix or Dragon Ball Z)
And the problem I'm having with the Angel series is it's not as interesting as the Buffy series. All four issues after reading them I'm like with this feeling of WTF? HOwever with Buffy after reading I'm just like damnit I can't wait til next month, Angel I'm just like blah.
Edit:
And according to Wikipedia Season Eight is going to be 40 issues.
Joss Whedon serves as "executive producer" for the series across every issue, giving his other writers notes on characterization, continuity and his overall concept in mind as he would when overseeing Buffy as a television series. Joss has written the first story arc, "The Long Way Home" (#1-4) as well as several one-shot stories (#5, #10, and #11), and is set to write the series fourth (#16-19) and final (#36-40) story arcs himself as well.
Comic and television writer Brian K. Vaughan became the first guest writer on the series, writing the second story arc "No Future for You" (#6-9). While Vaughan was not a "Buffyverse" staff member, he was a fan of both series (particularly the character of Faith) and Joss Whedon himself was a fan of Vaughan's Marvel Comics series Runaways, on which he served as writer during the period Vaughan wrote "No Future for You."
Former Buffy and Angel writer Drew Goddard writes the series' third arc, "Wolves at the Gate." Goddard first became a Buffy writer in its final season, starting with the episode "Selfless" and finishing with the Angel episode "The Girl in Question", which itself obliquely hints at the life of Buffy post-Season Seven. Goddard went onto become the a writer of the movie Cloverfield and acclaimed American dramas Lost and Alias (all working alongside producer J. J. Abrams) whilst also penning the story "Antique" for canonical Buffy comic book Tales of the Vampires, which he goes onto reference in "Wolves at the Gate".
Film, comics and television writer-producer Jeph Loeb is set to write issue #20 of the series. Loeb had previously been involved with Joss in the conception of Buffy the Animated Series, which never came to be. Following Loeb are Buffyverse alumni Jane Espenson, Doug Petrie, Drew Greenberg, Jim Krueger and Steven S. DeKnight who between them are set to tell the story between issues #21 and #29. One set of issues between those writers will serve to comprise one story arc told from a number of different perspectives. Issue #29 will be written by an as-yet unannounced writer, before Brad Meltzer, author of several New York Times best-selling books and later both Identity Crisis and Justice League of America for DC Comics is set to write the penultimate story arc of Season Eight, issues #31-35. Whedon himself resumes authorship for the final four issues of the series, bringing Season Eight to an end.
So basically we got another 3 years and 4 months of Season Eight
