do you think Jenova will be involved?

[KoShiatar]

Jenova *is* still alive, pretty much as long as there are Sephiroth clones around - and Cloud is one of them.
Remember the Jenova Reunion Theory: her cells will always reunite in the end, because they all share Jenova's will. And the Reunion the Silver Haired Boys talk about in the trailers is no other than a Jenova reunion, most probably.

aint it awesome

it says about lots of stuff in the trailer.

"Children are always the first to suffer.
Geostigma, Jenova.... Reunion."
"one man takes up his sword again" (something like that)
