Plural of Prius is "PRII", what will be the Plural of Nissan LEAF?

Toyota did a poll and after more than a million entries, the Plural of the popular Toyota Prius hybrid vehicle was voted by 25% of participants to be Prii. Toyota announced with pomp on multiple platforms the findings.


So one wonders, what will be the plural of the all electric Nissan LEAF? LEAVES, or LEAFS?
This is new territory here. We are waiting for the poll. Charlie Sheen may weigh in on this one.
