Although there's no way to determine what kind of device it will be just yet, it looks like LG will add something new to their repertoire soon. They just filed a trademark for something called the LG X5. We will keep an eye on this, but we hesitate to create a new section for it just yet. This may not be a smartphone, and it may not ever even get made. LG is notorious for filing trademarks on products they never follow through with.
We will keep an eye out just in case this turns out to be something concrete.
