Optical construction of the 16-85 is a tad more complicated (16 elements in 12 groups for the 16-85 vs 13 elements in 11 groups for the 18-135), so I guess the extra weight is due to the extra glass - perhaps to improve the 18-135 optical performance - and to get that extra 2mm of wide.
Be very interested in the lenstip or other reviews to see how it goes.
I do accept the extra 2mm at the short end makes a big difference, but cutting 50mm at the long end and at the same time increase price around 50% over the retail price of the DA 18-135, it better be an excelent performer on which IQ can be appreciated with bare eyes over a normal screen, THROUGH THE WHOLE ZOOM RANGE! If test show its IQ is very similar to the DA18-135 along the full comparable zoom range (18-85), or you actually need some pixel peeping to tell a difference, then this new lens is not worth a second look and should be priced below the $300 line, just to use it as an improved kit lens over the DA 18-55.
In short words, if its built like a "filet mignon" and priced like "filet mignon", then I expect "filet mignon" taste, not a Salisbury Steak from a frozen TV dinner...
