The word is two new letters are joining the Nokia line up as Nokia has now registered the Cseries and Xseries trademarks which cover mobile phones, replacement parts, smartphones, and accessories, so we are not too sure what these two new series will offer up.
According to an article over on GSMArena, they speculate that the new “C” could stand for Classic series or even “Computer” series due to Nokia and Intel working on something and could well fit into Nokia’s Connect category.
Then they speculate on this new “X” series which could mean XpressMusic, of course all this is guessing, but no doubt sooner or later we will find out for sure on just where and what these new Cseries and Xseries will bring.
