Hi Ste
Looking on the United Kingdom site, both the 7 and 7K are still showing as available and ready to buy so I would say it is still current so I would say you are safe. From reading a few sites, I have not found anything to say it is being discontinued.
Focus On Imaging is next month where various manufacturers announce new products. Like any general member of the public, I am waiting to see what is on offer mainly in relation to lenses from various companies so there could be more to come.
As for the 7, it is a very capable camera so I wouldn't worry about what comes out next since it is still very modern.
