I think this is a definite push for the kings. If the short stack wins even one pot at this blind level he'll surpass you. I don't think he can afford to wait for a better spot than this. Winning this pot will give him a comfortable stack, and he'll probably be able to bide his time until the short stack goes broke. I know there are special satellite bubble factors that make this close, but in this situation it looks like a push to me.
