I don't think kit building will go away.. But I do believe the number and variety of kits available will thin down. We'll be limited to the more commonly sold models by the bigger companies.

But we'll see less and less of the "uncommon" planes made into kits, simply because there won't be the demand. At best we'll see limited runs of these planes. That's why, when I have the money, I'm buying a US40 and US60 kit, even though I don't plan on building them for a couple years yet. Gotta get them while they're available.
