Fuji is rumored to hold a product launch event in the near future, most likely on June 19.
The new XF 18-135mm f/3.5-5.6 R OIS WR lens rumored to be announced on Mid-June, probably at this date.
The date is still not clear in the rumors because Fuji can change the exact announcement dates any time. This lens previously set for June than the announcement date again changed to May 26.
Now it is said to be announced later this month and the release date of the lens set for sometime in July 2014.
New XF 18-135mm f/3.5-5.6 R OIS To Be Announced Mid-June
The upcoming XF 18-135mm will be the first WR model to be announced this year by Fujifilm. The weather sealed XF 18-135mm f/3.5-5.6 R OIS lens will also provide long zoom for the weather sealed Fuji X-T1 mirrorless shooter.
The lens will offer a 35mm focal length equivalent of 27mm to 202.5mm. Fujifilm currently sells the X-T1 with a none weather-sealed 18-55mm f/2.8-4 R LM OIS lens.
Fujifilm has updated their X-mount lens roadmap in the beginning of 2014 and the new roadmap for 2014-2015 includes five new lenses. See all the details here for the roadmap.
