Yeah I don't expect the lease will change, at least not in the first half of the year (just my guess). They're really putting a lot of effort into the Options and the lease was a very recent, rushed additional option. (Excepting that, like you've pointed out, Options isn't even an option at all in Nevada or some other places.)
Here in Arizona, Options is an option. The rate is 2.25% for 48 months (though it's effectively higher than that due to the balloon), compared to the 0.9% on the traditional financing. The Phoenix market also gets a $1,000 cash incentive if financing with the Options plan.
For a buyer like myself, who is very unlikely to want to trade out after four years, that's not such a great deal. The lower rate financing is probably the better option.
