Don't get me wrong, but, honestly, I think that (also after having had a quick look at the questions) this is just pointless.

In a nutshell, what we know so far is that they announced a handheld device with something called "Jolla" that will be based on Mer. What they will do in the end is actually up to them.

We will see what it will be when it's done. To stress quite an old quote once more: "It's done when it's done.".
