(Medium credibility) Sigma will no more make X-mount lenses?

(Medium credibility rumor):

Fujirumors sources report that Sigma will no more launch any lens for the Fuji X-mount. Acording to FR Sigma motivated that decision with the following reason:

• Due the restricted market share, Sigma currently has no plans at all to release X-mount version of their lenses.

Well that would be very pit if true!
