Maybe Tracers return isn't too far away since I found this offer on eBay:

The seller tells us that he got the statue from PAX East 2017. As you can see on the shipper, the statue was made on 01-2017. Honestly I can't believe that they made only a few figures only for that event, so I guess that the next wave was finished in January and should be in the gear store soon. That would explain the little mistake when she was availabe back in February.
