Finally got to drive the new 2019 X1! Had my E39 in for service at our local BMW dealership and received the 28i as a complementary loaner vehicle. The customer service at BMW of Bridgeport is very, very good.

The 28i xDrive is currently $399/mo as of the BMW USA website.
However, the 2018 28i xDrive is only $319/mo which seems like a great monthly.
Of course, there are many variables that go into evaluating a lease deal such as the rates, residual, depreciation, total cost, and so on. But at a glance, the 2018 model seems to be a good rate right now for those in the X1 market.
