The most notorious prophecy states for Rand that 'To Live, You Must Die'.

 

We assume this is his death, along with the 'his blood on the slopes of dragonmount' (if anyone can post the prophecy itself that's be great because I can't remember it all and dont have the books with me).

 

Any chance he's already had his 'death' in the kind of rebirth that he had on Dragonmount in ToM?

I hope not. The main theme of the series so far is how Rand needs to sacrifice himself to save the world. If it turns out to just be some kind of metaphorical death or he comes back a couple days later or some crap like that, it would be an extraordinarily lame letdown to end the story on. I really hope that it means he'll live on in memory or his willingness to die means that he'll be able to be reborn again in the next Age to do it again or the like and they don't end up giving him some kind of cheesy happy ending.

The flip side to that would be that if he doesn't die, he won't live. Which might suggest the death required to live is a specific type of death... otherwise he'd still die and not be able to live. Just musing.
