I agreed with you Dominic. The promo is more revealing than any other. Maybe that is what they want us to think a possibility of Dean killing Jack. It also looks like something bad happens after the Jack and Dean confrontation. The Sky turns black and dean is looking at something. Maybe he does kill him and doing so messes up heaven or Jack or someone/something else did that.
