Three scenarios:
Kings play Vancouver if Vancouver wins, Dallas loses in regulation (making Canucks the top seed), Vegas wins and/or LA loses (making Kings WC 2)
Kings play Dallas if Dallas at least loses in OT and/or Vancouver loses (making Dallas the top seed), Vegas wins and/or LA loses (making Kings WC 2)
Kings play Edmonton if LA wins in regulation and Vegas loses in any way (Kings have ROW tiebreaker) or LA loses in OT and Vegas loses in regulation.
Canucks hold the tiebreaker over Dallas, and LA has the tiebreaker over Vegas. So it's still a little up in the air.
