Somewhere on this forum is a link to a non USA post by a website quoting LG about the massive update coming. Unfortunately, many of the items in the update list specific devices they will be included on, and the spectrum is not one of them. If you want to know what additions are coming to "some phones" search the internet for the LG optimus g hands on video. It is the same UI version, only many features are only coming to some phones.
LG Spectrum -- Rooted and running CM10.1 official M2 thanks to TDM (and too many others to list).
B&N Nook Tablet 16GB -- running CM10.1 with 10 finger multitouch
