From what I can see from the people who've actually talked to Zu about this, the Omen is at 1K now, will be at $1,500 eventually. That makes sense. The Superfly will be at $2,600, which also makes more sense than raising the price so drastically from $1800 initial orders to $3,500 for everyone else.
Now, my hunch is there's no need for the regular Soul, and that's why it's no longer mentioned on the website. The Superfly isn't described as a hot-rotted version of anything anymore - it does still say the Superfly is "an under the hood performance package", but it's not in comparison to a regular version. It's no longer an option, its a feature.
