Agreed, and the CSR I talked to on the phone yesterday seemed to know something but wasn't spilling the beans but did specifically say 'We always do presales on BIG releases like this'...it was in regards to if you preorder it you will still get the double data plan.
I interpret that as there will be some big fanfare and announcement and prerelease sales...I don't think that means we will get them next week but possibly preorder them.
Personally I think this whole thing w/ memory changing from 32g to 16g and the lack of an announcement all the way to technically issues is pointing more to logistical issues and on Samsungs side. There is a good possibility the first Gnex will be 32g and after that 16g for awhile at a lower prices because they are having supple issues (maybe Apple was smart and bought up all the 32g chips). This is all speculation of course but I don't think there is enough Gnex's on hand to meet a full in store release and they will start it w/ a big announcement....preorders, and then launch. I think it is Samsung that has been the issue.
