Just an update folks,
I ordered two nexus 5's (for wife and myself) this noon and just recently got the tracking number and shipping confirmation at 4pm.
But like others mentioned, still unable to track it on the yamato website so gotta wait for tenso also.
However, for those who's nexus status says "Leaves warehouse by November 8, 2013." or "Pre-ordered", you may want to click on the blue "info" text.
Seems like there is a difference in status. Like mine says "shipped" in one page (one with order number) while another simpler page says "Leaves warehouse by November 8, 2013." and "Pre-ordered" for the 2 nexus i got.
