RoTS Anakin & Obi-Wan vs Volturi

Anakin and Obi-Wan are with the Cullens (and their allies) and are trying to reach a peace deal with the Volturi. The Volturi sense the two Jedi's power and attack. Do the Jedi survive or are killed?

They are killed in seconds.

These two jedi die very quickly.

they all die of aids

stalemate

sensing the jedis powers the volturi might try to change them into vamps to join their clan. they respect power and dont actually attack straight away without considering it first. could you imagine anakin and obi-wan being changed and having vamp powers as well? how hard would they be then?
