I wonder too. I just placed an order.
Tested "unofficial" 3.0 and 3.01 here in Edmonton, Canada and I'm not impressed with the maps update. For some reason all Provincial highways are referred to as KINGS HWY (That's a name they used to have in Ontario in the past). For Example Queen Highway 2 is being called KINGS HWY 2, Yellowhead Highway 16 is called KINGS HWY 16, Anthony Henday Highway 216 is called KINGS HWY 216. etc.... Very, very annoying!
I hope they sorted it out in the "Canadian" update.
