I don't think you're going to get accurate answers from either Ducati or the dealers. However, don't assume this means they don't know...
The fact that the Ducati uk rep at the Scotish show told you to speak to the Glasgow dealer suggests to me that the plans for which dealers are going to get what, and when, are well advanced. Ducati themselves can't be in the dark about their production schedules, but they wouldn't want to say anything that might contradict what their dealers have said to their customers.
From the dealers prospective they aren't going to make promises to you that they aren't certain they can keep. Lets face it, you might be disappointed if you're told your 1199 is a bit delayed, but you'd be a lot less happy if your dealer told you your bike was going to be here next week and then it didn't show up. If they set expectation low, they can call you with the unexpected good news when it does turn up on time. Besides, the dealers know that if you drop out, there are plenty more in the queue.
Let's wait and see. I predict the first 'my bike is here' report will be before mid-April.
