The Fujifilm X-A5 is shipping from B&H Photo, Amazon, and Adorama at this time and already almost completely out of stock at some retailers. If you’re interested in the Fujinon XC 15-45 grabbing an X-A5 is honestly the better option than waiting until March for the XC 15-45, because you get a pretty good body for $200 more. Just remember XC lenses are a step below XF lenses so if you do not have high expectations for this lens beyond functionality than you should be pleasantly surprised by its performance.
