Hopefully you won't have to wait as long as that, as about a week after placing your order your dealer should contact you to confirm the provisional build date he will have received from SEAT.
Although I was originally given a date of 1st May, I have now been informed that it will actually be built in week 3, which will only be about 6 weeks after the order date.
Of course this could well change before then, and will still take a few weeks after that before it reaches my dealer.
However as I am not looking to pick it up before 1st March 2017 anyway, I am hoping that it will work out about right for me... but we will see!
Fingers crossed!
