At this point, being the final outing and with the people involved (Abrams, Kennedy, etc.), I can wholeheartedly believe the "hey, could happen" stance. There's no telling what off-the-wall, out-of-nowhere approach they'll attempt with this thing.
If we get out of this movie without time travel, clones, dual-alternate timelines or universes, bad dreams, major fake-outs (Han IS alive - he survived the stab, the fall and the planet exploding! - and he throws Rey his blaster when she needs it most!!), I'll eat my hat.
I don't trust these people...I just
don't
