Quoted from Motorcitypinball:
4. Flash Gordon
5. 8 Ball deluxe or Paragon (Tie)
Paragon is AWESOME, but it's so brutal that I'm not sure how much it would benefit from 2.0 rules. I feel like I don't keep the ball alive long enough to be able to explore deeper rules, even though there is certainly a ton of things to shoot that could be incorporated into new rules.
On the other hand, Embryon 2.0 would be so dope! Also tons to shoot for, but much less brutal ball times.
All that said, I'll be surprised if they do wide bodies. I'd also be surprised if they did Flash Gordon due to licensing / split playfields.
I would expect that they'll stick to single-level standard-width games. However, the list gets pretty thin, pretty quickly, in terms of justifying the $9K cost.
Fathom and Centaur are no-brainers. I'm guessing they'll do 8 Ball Deluxe, but I wouldn't buy it. Maybe Xenon, but the playfield is so barren, so again I wouldn't buy it.
Skateball would be amazing, but $9K?
