Yah it'll come down, but do you really want to be late to the party??
Or do you want to finally be an early adopter, able to make sweeping SQ reviews where fellow Head-Fiers hang on your every word?
Personally I'm probably going to buy these as soon as they come out and likely sell the 840s. I like the 840s a lot (though I'm thinking crazy thoughts about buying the LCD-2) but these ones go to 11 -- velour, wanky silver plastic, "bumps," hidden wires, oh my!
But yea, I'm looking forward to the sound in comparison to my 440's less fun, probably, overall sound improvement, definitely.
