Her death to me didn't seem very convincing. About 85% of Tumblr/Facebook/Twitter users I've saw think she isn't really dead. Plus Rebecca didn't tweet anything like "I've had such a wonderful time on the show" she only said "I hope you enjoyed it" and she's always going on about how much she loves being on the show, so for me it looks like she's still alive. My friend guessed she was sent back to Oz or the EF somehow.

I'm still hoping.

I wasnt really convinced either. The green fog looked like it was her soul. (Lame I know)

I believe that we'll still see some of Zelena in the past or in flashbacks, but I believe the smoke was just Zelena's magic being released once she was killed.

Though I do believe that maybe while Hook and Emma are "time jumping", they can do something to prevent Zelena's death - like alter something so Rumple either chooses not to or is prevented from killing Zelena.

Zelena is in the first part of the finale in case anyone is wondering by the way.

me too i want her to live

I want her to be gone. Forever. Whether Regina gave her a new life or if Rumpel ended her life, I want her to be GONE. But she's probably still alive >.<

I want her to come back, she was perfect
