Latest Fantastic Four Teaser Shows...Five Members?

Latest Fantastic Four Teaser Shows...Five Members?: "
We've been getting a different Fantastic Four teaser each day. The first was just the logo, bringing speculation over the return of the team in November. The second showed the current team (along with Spider-Man) in their Future Foundation outfits. Then we had a Joe Quesada piece with the original team, including the Human Torch, who we know is currently dead.
Today Marvel has released a fourth teaser...

What does this mean? Now we know for sure that Fantastic Four #600 is indeed coming out. But what about Johnny? How does Spider-Man fit in? Can the team still be the Fantastic FOUR if they have five characters? Guess we'll have to wait until tomorrow to see what the final teaser shows us.
