I have noticed that the Japanese press release includes an information that the English press release (shared here) does not include: the approximate release of the lens.
Tamron Japan says that the Tamron 11-20mm f/2.8 Di III-A RXD for Fujifilm X will be released in Spring 2023
Specs, Price & Performance
The lens is already listed at B&H Photo here.
As far as specs and price goes, Tamron has not disclosed details (except for the few available in the press release).
And yet, if we look at the Sony E mount version of this lens we should get quite an accurate idea what to expect.
As for its performance, here are the customers reviews for the Tamron 11-20mm f/2.8 for Sony E mount.
