"SmashGAF, the only place where more than 40 means less than 50!"
I kid, but seriously don't be so quick to jump to conclusions.
I've heard dozen of times how there were no other newcomers aside from those of the Gematsu leak and how the Gematsu leak and the RosalinaX rumor lined up so perfectly. Some of you (one in particular

) were adamant about the E3 e-mail implying no other newcomers other than those listed.
After Robin was revealed some were so fixated with the leak to end up thinking all kind of weid happenings to justify Robin and Lucina as replacements for Chrom and Shulk, with still no other unleaked newcomers to come.
Now we have a new and more accurate leak and you're once again all jumping on the "it's confirmed, that's it, no more characters" bandwagon.
No matter what, it's still a leak. That could be final, but it could also not be. And don't tell me: "b-but everything points to that roster being final!"; I'd agree with you if I didn't hear these same words uttered for the Gematsu and RosalinaX leaks as well.
