In the wiki 'about' Mer, I can't understand this section:

"Does Mer replace Diablo/OS2008 ?
Well...
Nokia won't be upgrading 2008 anymore.
We're talking to see if there could be an official handover (SSU) to 'community support' but nothing concrete yet.
So in that sense, Mer will be one option to updating your tablet if you want something that is either broken, or not in, OS2008."

If you want something that is either broken, or not in, OS2008?

Apart from that, when is the 'finished' Mer expected to come out?
I know 'finished' is an odd term to use maybe for something that may evolve but 'finished' in terms of stable, etc. Version 1.x I guess.
