This was in the email I received from Gerry along with the video:

Our new promo video just went live: &feature=youtu.be

There are a couple of important things to point out:

1)  This video shows a number of ways game designers can make use of the P3's modularity to vary the physical shot layouts and features in their games.  People have long questioned how versatile the P3 could be with only the upper playfield section being swappable.  Hopefully it's now clear that designers can implement practically any feature seen in pinball before, and they can do it just about anywhere on the playfield.  It just requires a different way of thinking and in some cases some new engineering.  We've obviously already floated the flippers and slingshots over the playfield.  Floating pop bumpers and inverted scoop-type-features are coming, as are floating targets, spinners, and even ramps.

2)  Lexy Lightspeed - Galaxy Girl now has an episode name: "Escape From Earth".  This, combined with a new intro animation in the game, should allay the confusion about Lexy being a Galaxy Girl and the game being based on Earth.  As you've all seen by now, we operate backwards from most pinball companies.  We focused on making our machine (the P3) and first game (LL-EE) functional and playable first.  Then we started making them pretty (artwork, game/mode introductions, etc).  In short, Lexy and Lookie are shot down by the evil agents in Area 53.1 (deep in the Florida swampland).  Gameplay is centered around helping them escape.

Texas Pinball Festival, here we come!  Hope to see many of you there.

And this is from a new thread he created on Pinside:

Hi all,

We've received a lot of feedback about the modularity in the P3, and many have had questions about whether or not the upper playfield region is enough space to provide significantly different playing experience. While we believe it is, we've also discussed the ability to add swappable mechanical features anywhere over the entire playfield, and we've been promising conceptual images to illustrate this.

Game designers have more freedom than we can easily explain in short messages or videos. Suffice it to say, they can create just about any feature that exists in current pinball machines... they just have to think about it and engineer it a little differently.
Also note the game name change to Lexy Lightspeed - Escape From Earth. She's still Lexy Lightspeed - Galaxy Girl, but in this 'episode', she's battling the evil agents of Area 53.1 to escape from Earth and return to her adventures in space.

It's time for pinball to evolve!
