Think big picture.
Kings/Sharks both have 6 points from their season series, so let's call that a wash. They're equally likely to win the game. So then you have to look at scenarios involving Phoenix.
If the Kings win in regulation, they win the division if Phoenix gets 0-3 points.
If the Sharks win in regulation, they win the division if Phoenix gets 0-2 points.
It's more complicated with LA vs Phoenix and I might actually be wrong. I'm sure there's a site out there that has the actual odds.

Assuming all instances above have equal potential of occurrence:
42 total outcomes
9 instances of Sharks Division win
14 instances of Kings Division win
19 instances of Phoenix Division win
Using equivalent weighting of potential ending outcomes, Phoenix is the most likely division winner. However, assuming equal weighting of ending results is a bit weird.
It is odd to think of the above as all having equal weighting. We could come up with weighting of regulation wins and losses vs OT and wins and losses vs SO wins and losses. However, whats to say we shouldn't start weighting home games vs away games, prior records of upcoming opponents, etc?
Whats your preferred set of other factors, and what importance would you put to them? For instance, if we assume a higher likelihood of one of the above outcomes results from number of home games, San Jose would be in excellent shape considering LA will be away and all Phoenix games remaining are on the road.
