I've been checking too, there's still no sign of a pre-order bonus :sadvaultboy:
I've been checking Amazon.ca daily and even emailed them 3 times already, to no avail. I still have my preorder in (because I need an order # just to contact them) but might very well cancel it eventually and switch to D2D.com to get my hands on a PC version of the game (and buy my PS3 copy at ebgames I guess).
In their last email, I was referred to Bethesda for info (and have yet to receive an answer from them a week later).
