If it follows the pattern of the pre FL, decent discounts could start to appear early next year once all the early adopters orders are dealt with, demand calms down & Dealer allocations become readily available.
You've gotta accept that early cars are gonna command a premium.
That's why I've been waiting, early cars might have some little problems here and there too. If you can get 2-2.5K discount from brokers now, hopefully by early next year (I remember someone mentioned right after Christmas being a good time too), you'll be able to get 3-4K off, maybe even 5k.
