It's sorta announced, expect n9 late september-ish. Dunno about the SGSll, but when the n900 came out it was one of the best out there sound output quality wise and I bet you won't hear much difference from the best handsets of today. It still is good, there are even mods to improve it or make it louder. You might consider using the N900 as audio player for it haz more EMMC space by miles.
