Don't choose Yes because you want your ship to live happy ever after. I think somehow it will ruin the show if it happens. Vampires are a big part in TVD.

I think that at the end of the season Elena, Damon and Stefan will be turned to humans again. Through the season 5 they will be struggling with their new lives, and then for season 6 (the last season), they will be vampires again.

@NocKairu interesting theory

It's The VAMPIRE Diaries, so I didn't sign up for some stupid, lame cure. But I expect it to be not what we are supposed to expect from it, just like the sun and moon curse, so I don't worry yet.

Elena for exemple... It's the only one that I want to turn human again.
And maybe.... Tyler.

VAMPIRE diaries... i watch this show to see vampires.

No way in hell!

maybe one of them only but it only lasts for a day or something.

Maybe anly one or two, but it would seem stupid if half of the vampires turned human - I don't even think half of them know how to be human if it came to that..
In some way I would like Klaus to be turned into a human as a punishment for all the crap he's done - mostly to Rebekah - it would be a nice revenge somehow :)

I expected this "cure" thing to come at some point of the show, especially now that Elena is a vampire.

NO!!!! the only time they can do that is when they do flashbacks. If one turns back to human that is okay, but not all of them.
