It will certainly be a challenge to create a fun and exciting game of pinball on a single level. Not all games need ramps, but a game that features all the Bonds, all the villains, and all the movies?... You most definitely need ramps to do the theme justice.
I suspect they will rely heavily on the LCD mounted in the playfield, to dazzle the player. Best place for the screen in an all-action game, as I demonstrated in my Bond game, a decade ago (and later in Alien at Heighway). You don't miss a single frame when the screen is at eye level, but it only works well with very clever coordination, which matches movie clips and animations with the action on the playfield.
So yeah, if they nail the LCD integration and offer a fully immersive experience, then you won't even notice the game has no ramps.
