Sony Japan has announced that the NEX E-Mount 18-200mm lens (which is packaged with the Sony NEX-VG10) will be available in September 2010 for 99750 yen for other NEX-format cameras; however, US pricing should be in the neighborhood of $800-900 as a best guess.
No word yet on availability stateside, or official US pricing for that matter. It’s a good sign that we’ll see the E-Mount 18-200mm lens on NEX-3 and NEX-5 cameras soon though.
I got a copy of a sheet that was provided to vendors when I got the camera about a month ago. It shows all the available and soon to be available accessories. The 18-200mm lens is listed at 899.99
