The only possibility I can see that might be what you're looking for would be if they offered a "collector's edition upgrade" for Ea testers as the final launch date of the game approached. This would give you any CE perks and extra, and you would pay the difference in price, at best ideal.
This isn't something that Larian have yet commented on, and I doubt they will until such editions are actually available to be purchased, but I feel it's unlikely to be a thing, I'm sorry to say.
I'm sceptical as to whether they will even do a hard launch of any description, to be completely honest.
