Is Turbine in over its head with the coming Expansion ?

[AC_Guy]

From what I have read so far there are major changing coming but my main concern is CONTENT.

Will Turbine still be able to provide us with content over so many diffferent Level ranges ?

Or will the Sub 126 game suffer for 6 months after the expansion hits?

most of the large dungeons, like Blackmire 1, 2, 3, Gaerlan, and so on, have several portals into it with level ranges and all, So I am betting all new dungeons developed after the expansion will still be balanced properly.
