Death Saves

So this week in D&D Encounters we had a player drop to negative 10 Hit Points--yes, I am that much of a Bad Ass DM!

I am not sure exactly what the death & dying rules are for D&D Next? In 4E, Negative bloodied was dead dead--is that true in D&D Next? 

If a player is negative hit points do they still make death saves during their turn in Next?

Any tips on how this works would be helpful.
