How long will I wait?

I've been reading posts about how long the wait will be for an odyssey. I ordered my van a week before the earthquake and was given a delivery date of April 23. I can't find out any information as to when my van will arrive. The dealership told me that no vin has been issued. I called Honda Canada and they cannot give me any information which I find to be quite strange. I would expect that they would have some kind of idea as to if I'll be waiting one, two, three or more months but they maintain that they can't tell me anything. We have a long road trip planned for the end of August and I do need our vehicle by then. Can anyone please advise? Thank you.
