(judging only from the 2 minute Premium teaser)
I'm not going to comment on the artwork, it's all been said for me by others, and art comments are mostly subjective.
(If I thought this was off-the-charts awesome like Dirty-Donny's hand-drawn Metallica playfield, then I'd say so.)

I look forward to watching a half hour of actual game play to see how the ball behaves, and how long the ball times are. I don't have any concerns at this time about how it will shoot. SR knows angles. I like spinners, drops, horseshoes, and middle ramps that can be hit by both flippers. It has some of these.

I do have one question that I have to ask about "most" modern game designs: (bear in mind, I'm not a code guy, I'm much more of a ball-travel guy)

This question has been asked dozens of times by many people over the last 10+ years:

Q: How does this "safe-version" of a "pop pen" add fun to the game?
A: (rollover lanes?) is often a half-answer, but I don't see any rollover lanes on this one.

SR, why are you holding up my ball with pops with no risk for a drain?
Stern, why do you keep putting "safety-first" walled-off pop pens in games?

Hopefully from the upcoming game-play video, we'll see a ball that doesn't get held hostage for too long, but c'mon -- playfield real estate is so precious -- every square inch, I just don't know why pops are ever there unless they add: ACTION and DANGER.

As always, look forward to playing it...

Imagine a band, so talented -- that they don't have to rely on visual gimmicks to be loved.
