No, what you assumed was that there would be deep discounting of all 680s across the board.
Nothing in the first post of this thread says that there is discounting of 680s "across the board", and the OP linked specific models that were on clearance with an aside at the end suggesting that any potential buyers wait (unless for SLI). FFS, learn to read...
Title of post states that 680s are being clearanced.
First sentence of post gives "one example".
Goes on to state "Newegg is running some at steeply reduced pricing as well." Some. Not one.
