Jolla may not be huge in the smartphone market but does attract a serious amount of attention because it's made up of former Nokia employees and uses Nokia and Intel's old lovechild MeeGo OS in the form of its Sailfish OS.
It has just one product so far - the midrange Jolla - but has just teased on Twitter and its website that "Something BIG is about to begin" November 19.
The teaser has a counter leading up to the date and what looks like the edge of some device which we can only guess will be either a new Jolla smartphone or, judging by the BIG in the teaser, a phablet or tablet running Sailfish OS.
We can't tell much by the teaser but we can conclude that the hardware design will be different.
The countdown to something big begins now. Sign up at http://t.co/A5ZkqgLuTp #jolla #unlike pic.twitter.com/QU5rMl4zjj
