I love the book and think it'll do well long term like Saga, but just based on how many there are, i can't fathom it climbing beyond $100 in 9.8. Just too many out there.
I'm also not a variant chaser, but considering the print run, I definitely think the retailer variant will be the big draw. Should be a 350-400 book for a while. Hopefully there will be a big jump with the TPB. Either way, I have no idea why you wouldn't buy a retailer variant right now. At worst, you get your money back selling it raw.
